Add them to get 2x=-16, x=-8, substitute in either to get 4y=0, y=0.
x=-8
y=0 ;
Using the elimination method, we found that the solution to the system of equations is x = -8 and y = 0. This was achieved by subtracting the two equations to eliminate x, leading to y = 0. Substituting y back into one of the original equations gave us the value of x.
