Answer 1

Answer:

x = 15 (D)

Step-by-step explanation:

First, we distribute the -1/2:

-1/2 x x = -1/2x

-1/2 x 5 = -2.5

Now we have -1/2x + (-2.5) = -10

Move the variables to one side and the regular numbers on the other (in other words, subtracting both sides by -2.5:

-1/2x = -10 + 2.5

-1/2x = -7.5

x = -7.5/(-1/2)

x = 15   (D)
