You could also say that the value of X=20 and Y=10. Proof: 2(20) + 5(10) = 90 and 3(20) + 3(10) = 90

Sir in the last example, why is that the value of y is solved first before the value of x?

Hello I solved for y because it was convenient for me. You are free to solve for x first if you want.

Ahhhh, so you mean sir that the answer would still be the same.?

Im not getting why you multiply equation 1 by 3 and equation 2 by 2? Is it just arbitrary?

I am using the elimination method you need to get the coefficient of a single variable to be equal and opposite sign and then add so that they eliminate. 6 is s multiple of 3 and 2.

@@MathFortress Oh!! I dont think Ive ever learned that. Thanks for letting me know. Your videos just took me through geometry in 2-3 days, many of the things i didnt understand back in school, but now do. Big help😁👍
