Use the Substitution method to solve the system of equations.
x + y = -4
x - y = 2
x + y = -4
x - y = 2
In the second equation,
x= y+2 Putting that in the first..
(y+2) + y= -4
subtract two from each side, then divide each side by two to get y. Then, put that value of y into EITHER of the equations and solve for x. I will be happy to critique your thinking or work.
