ax+4=2y+8
bx+2=4y-11
In the equations above, a and b are constants. If a is 3 minus b, which of the following is true?
A) x is y minus 9
B) x is y minus 3
C) x is twice y minus 9
D) x is twice y minus 3
I have the answer (D), I just have no clue how to solve this. I've tried substitution and elimination but there are so many variables. Do I try just putting numbers in for a and b? I've tried every which way to solve this, but the right way it seems.
