Given the equation:

-2x + 3  = -15

Determine the value that makes the equation true.

Solution:

In order to determine the value that makes the equation true, we simply need to solve for x.

Transpose 3 to the other side of the equation, and then combine similar terms.

-2x + 3 = -15

-2x = -15 - 3

-2x = - 18

Divide both sides of the equation by -2 in order to cancel out -2x leaving behind x.

-2x/-2 = -18/-2

x = 9

Final answer:

x = 9
