Question

What value of x satisfies the equation below? -2X - 7 =12

Answer 1

-2x - 7 = 12

Adding 7 at both sides of the equation, we get:

-2x - 7 + 7 = 12 + 7

-2x = 19

Dividing by -2 at both sides of the equation, we get:

$\begin{gathered} \frac{-2x}{-2}=\frac{19}{-2} \\ x=-\frac{19}{2}=-9.5 \end{gathered}$
