What is the solution to the system of equations? Use the substitution method to solve. 6=−4x+y −5x−y=21
6=4x+y -5x-y=21 y=6+4x y=-5x-21 6+4x=-5x-21 6=-9x-21 27=-9x -3=x
x=-3, and y=-6. To show how you worked the problem, you would have to move around one of the equations, and then substitute the variable.
