X - 6y -- 2: = -8
--x + 5y + 3 = 2
3x - 2y - 42 = 18

1. Subtract first equation from second equation:

y = 7, if that first step is simplified.

2. Substitute y = 7 in any of the equations. (I am substituting in the first equation) :

You will get your x, which is x = 36

So now that you have your x and your y, you have finished solving the equation.

The answer is:
(x,y) = (36, 7)

Hope this helped! Have an awesome day!!
