Question

Solving systems using subtitution y=2x-10
2y=x-8

Answer 1

First you plug the y=2x-10 into the y for 2y=x-8
This will give you 2(2x-10)=x-8
4x-20=x-8
3x=12
answer: x=4

Answer 2

sub the first equation in to the second.
2(2x-10)=x-8
solve normally
find x=4 then sub into first equation to find y
