Step 1: Take away 4 on both sides so there is an x and a number on one side 3 x + 4 = 19 -4 -4 Step 2: You subtract, and make your new equation. 3 x = 15 Step 3: Once you have your x and number on one side of the equation, you can now divide the number by it's x, and you will get your x. 3x = 15 ÷3 ÷3 x = 5 I hope I helped out a bit. 😊😊😊
2) Solution(with some explanation):- 3x + 4 = 19 then we will transpose 4 (also we can call it as the additive inverse of 4) then, 3x = 19 - 4 = 3x = 15 then we will divide it by 3 then, x = 15/3 = 15/3 is 5 So, the x = 5 Done 👍✔️✔️
Another way to js solve this is to grab a calculator and replace the X with a number that will get you to 17. For ex , 2(11)-5=17 will give u 11 . As u can see I just replaced the X with a 11 in order to get me my answer . Hope that helps .
Unfortunately using this method will take the equation to be simplified in a much less efficient and productive way. As shown in the short, by far, it is the most commonly used method to solve linear equations, however there are more methods such as turning the integers positive or negative value into their corresponding opposites then placed into the other expression. Nevertheless this method is possible and usable, but not as much as the actual way to solve it.
If you looked at the comments for further explanation or don't understand the vid, do this trick I learned, 2x - 5 = 17 2x = 17 + 5 2x = 22 2x = 22 2. 2 X= 11
Romans 3:23-24 Jesus is the only way to HEAVEN☝️ You are Created by God to Loved God and to be Loved by God! Always remember that! We all have sinned and deserve to perish in Hell, but because of God's Mercy and Grace he send his only son Jesus to Sacrifice on the Cross to saved us. 23 for all have sinned and fall short of the glory of God, 24 and all are justified freely by his grace through the redemption that came by Christ Jesus. Repent and Return to God everyone Jesus is coming back soon here on earth to Rapture the believers my bro/sis, what you need to do is to Repent from all your sins and believed that Jesus died on the cross to sacrifice himself so through that their is forgiveness of our sins and God raised him from the dead to overcome death to have evelasting life, accept him as Lord and Savior of your life, pray right now asking for forgiveness and guidance, and study the Bible. Amen! Glory to God! God bless!
Bro this guy Is just making this hard just throw the -5 to the other side which makes the-5 as 5plus 5 which makes 22 and put it as 22 by 2 he's just making it harder
I know it's probably a dumb question, but why don't we add 5 to 2x? Is it because it is impossible as x is an unknown so adding 5 to it would not work?
The secondthanks God i know actually im slow learner about math than science but when i watch yt about equations i learn now maybe bit 3x+4=19 -4 -4 this +4 become subtract because you reverse on subtract from addition look at the below ⬇ because you reverse just see in the last of this solving just scroll down in the last -4 -4 cancel +4 -4 then bring down the 3X then 19 minus to 4 is equal = 15 ↩↩↩ ↙ 3x=15 then 3 X = 15 ↗ ---- ---- ↪ 3 3 Cancel this 3/3 Then bring down the X Then after 15 are divided to 3 the answer is ↘ ↘ ↘ X=5 answer im right? Just undo like this ↘ ↘ ( ) groups or parenthesis ² X Exponents ⬇ X ÷ ⬇ + - ⬆ ⬇ ⬆ ⬇ ⬆ ⬆ undo reverse
X=2×-5=17 ×=2×-5+5=17+5 ×=2×(0)=22 ×=2×=22 To check: 2×-5=17 (22)-5=17 17=17 I do not know if thats mutiplay addition subtraction or divide when addition subtraction when subtraction addition when mutifly division when division mutifly i em not joking from what my teacher teaches us
This is really nice. But I think it is explained way too fast, like as though you are trying to limit the video's length to fit the youtube's shorts requirements. Can you slow the video a little and post it on a regular RU-vid format? This is valueble. You're like the only one who explains it best. I just wish it was fast enough to understand.
Sir I have a question. Q) The sum of 3 consecutive multiples of 11 is 363. I need to find these multiples. A) let x = multiple of 11, then next multiple is x+11,next multiple is x+22; giving us equation of x+x+11+x+22= 363 Solving it, we get x=110,x+11=121,x+22=132. Alternative we can take multiple just before x,as in, x-11,x,x+11 giving us equation as (x-11)+x+(x+11)=363 giving us x=121,x-11=110,x+11=132. Doubt) Why can't we take two multiples before x? As in x-22,x-11 and x? Because when I do put it in equation, answers come out wrong,for eg x somehow=131.
Hello, i have the answer for your question. the answer will be 110,121,131 how you do it: Let the three consecutive multiples of 11 are 11x, 11x+11 and 11x+22 Their sum is 363 11x+11x+11+11x+22=363 33x+33=363 33x=363−33 33x=330 x= 33 330 x=10 First multiple =11x=11×10=110 Second multiple =11x+11=110+11=121 Third multiple =11x+22=110+22=132 hope this helped😊
correct you isolate x on one side which would give you 2x -5=17 then add 5 to both sides giving you 2x-5=17+5 which ofc equals 22 and then you divide both sides by 2 which is 11
