This video helped me sooo much, thank you! I was stuck on a similar question like example 3 and I couldn’t figure out how to solve it after watching numerous videos. But after I watched this one, I finally understood!😊
hi, during the 10x + 49 = 3x - 30, i was just wondering why you can’t just combine like terms ? because in some situations you need to combine and in others you need to subtract. why is that? is combining like terms only for linear inequalities?
Because of you I'm clever student from my school thanks thanks keep it up I love you so much ❤❤❤❤❤❤❤❤❤❤❤❤❤🎉🎉🎉🎉🎉🎉🎉🎉 Please teach us about vector direction
7:00 why did you choose second equation instead first equation? 9:28 why did you choose second equation instead first equation again? I still cant understand
Why did you choose the second equation instead of the first equation? It is because the coefficients in the second equation are smaller numbers compared to those in the first equation. It is easier and faster to work with smaller numbers. However, you can also use the first equation and you will get the same answer. Why did you choose the second equation instead of the first equation again? It is because Y is already isolated in the second equation, so you can find it with fewer steps and save time. If you use the first equation, you will get the same answer but it will take more time as you need to do more steps.
