Solve by using elimination. Express your answer as an ordered pair.

-4x + 4y = -12
7x - 4y = 24

the 4y’s cancel out

3x = 12

divide by 3 to get x by itself

x = 4

plug your x value into either of your original equations

-4 (3) + 4y = -12
-12 + 4y = -12
4y = 0

y = 0

(4,0)

you can check your answer by plugging both the x and y values in

-4(3) + 4(0) = -12
-12 + 0 = -12
-12 = -12

this statement is true so we can confirm the answer would be (4,0)

The correct answer is -4
