.
y = -3x       (1)
y = x-8       (2)
-------------- 

If you want to solve it, you can immediately see that

-3x = x - 8  (3)

follows from your equations. 
It is because the left sides of these equations are identical - so the right sides are equal too.

Now solve (3) and then complete the assignment.
