To solve a system of equations, you can either graph, substitute, or use elimination. The easiest method for this problem will be elimination:
Add the two equations together to eliminate y:
x + y = -6
11x - y = 42
------------
12x + 0 = 36
Now solve like a one step equation. Divide both sides by 12.
Reduce.
Now plug in this value of x to one of the equations:
Subtract 3 from each side.
Reduce.
x = 3
y = -9
