$x = - 22$ $x = -22$

$- \frac{1}{2} x + 12 = 23$ $-1/2x + 12 = 23$

First, subtract 12 from both sides of the equation. This results in:

$- \frac{1}{2} x = 11$ $-1/2x = 11$

Then multiply both sides of the equation by $- 2$ $-2$ so that the $x$ $x$ is all that remains on the left side of the equation:

$- 2 (- \frac{1}{2} x) = 11 (- 2)$ $-2(-1/2x) = 11(-2)$

Therefore,

$x = - 22$ $x = -22$
