So we can either use the substitution method for x or y. Let’s do x To isolate x in equation 2, we subtract y from both sides to get X=-12-y Now we know what x is in terms of y and an integer. Plug back in 2(-12-y)-3y=6 -24-2y-3y=6 -24-5y=6 -5y=30 y=-6 We have the value of y now. Let’s substitute it into the second equation. X-6=-12 X=-6 So the solution is (-6,-6)
