Question

Solve this system of equations using substitution. Put your answer in ordered pair form, (x, y).

x - 2y = -4
2x - y = 1

Answer 1

x=(2y-4)

plug to other equation
2(2y-4)-y=1

4y-8-y=1
combine like terms
3y=9

solve for y
y=3

that's your y-coordinate

plug into any equation for x

plugging into first

x - 2(3) = -4

x -6 = -4
x = 2

so the solution is (2,3)
