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
