Answer:
10 or x=10
Step-by-step explanation:
First we can combine like-terms.
8x+6=86
Then subtract 6 from both sides
8x=80
Divide by 8
x=10
![-6x - 4y = 12|\div 2\\ 12y = -18x - 36|\div 6\\\\ -3x-2y=6\\ 2y=-3x-6\\\\ -3x-2y=6\\ -3x-2y=6](https://tex.z-dn.net/?f=-6x%20-%204y%20%3D%2012%7C%5Cdiv%202%5C%5C%0A12y%20%3D%20-18x%20-%2036%7C%5Cdiv%206%5C%5C%5C%5C%0A-3x-2y%3D6%5C%5C%0A2y%3D-3x-6%5C%5C%5C%5C%0A-3x-2y%3D6%5C%5C%0A-3x-2y%3D6)
Both equations are equivalent, so there are infinitely many solutions.
