Question

helper will get a medal!
3x + 2y = A
5x + y = B
Eliminating the variable y from the system of equations results in -7x =
A - 2B
2B - A
A + 2B

Answer 1

how do you think you would get rid of y?

Answer 2

its been a while since ive done these problems uh... doesn't it have to be opposite of the other y to cancel it out?

Answer 3

\[\text{Eliminate}[\{3 x+2 y=A,5 x+y=B\},\{y\}] \]\[A+7 x=2 B \]-7x=A-2B

Answer 4

you still need help?

Answer 5

@legomyego180 oh no, i got it, thank you! :)
