Solve the system of equations using subtraction.
2x−4y=−4
2x+ y =11

(4, 3 )

Step-by-step explanation:

2x - 4y = - 4 → (1)

2x + y = 11 → (2)

subtract (2) from (1) term by term to eliminate x

(2x - 2x) + (- 4y - y) = - 4 - 11

0 - 5y = - 15

- 5y = - 15 ( divide both sides by - 5 )

y = 3

substitute y = 3 into either of the 2 equations and solve for x

substituting into (2)

2x + 3 = 11 ( subtract 3 from both sides )

2x = 8 ( divide both sides by 2 )

x = 4

solution is (4, 3 )
