Answer 1

Plug in the values of x and y into the formula, and if both sides are equal, it is right.
a. 5(0)+(-5)=-25
0-5=-25
-5=-25
They are not equal, we can rule out A

Answer 2

b. 5(-6)+0=-25
-30=-25
They are not equal, we can rule out B

Answer 3

c. 5(0)-6=-25
0-6=-25
-6=-25
They are not equal, we can rule out C

Answer 4

-25=-25
Equal!! D is the answer
