(IF SOLVING FOR Y) y= x/2+2
(IF SOLVING FOR X) x=2y-4
First you need to combine like terms
13x+8-15x=6+x+11
-2x+8=x+17
-x -8 -x -8
-3x=9
--- ----
-3 -3
x=-3
I hope I've helped!
![\frac{1}{2} / \frac{3}{1} = \frac{1}{2} * \frac{1}{3} = \frac{1}{6}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%20%2F%20%5Cfrac%7B3%7D%7B1%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%2A%20%5Cfrac%7B1%7D%7B3%7D%20%3D%20%5Cfrac%7B1%7D%7B6%7D%20)
