Victor Franklin · Answer 1

Yes

Step-by-step explanation:

If you plug - 2 in for X and - 4 in for Y, you get 8 * (-2) - 7 (-4) = 12 ⇒ - 16 + 28 = 12

You get 12=12 which is true.

Carley Peters · Answer 2

Yes because if you plug in - 2 to x and - 4 to y, you get 12.

8 (-2) - 7 (-4) = (-16) - (-28) = (-16) + (28) = 12
