Answer:
x = -12
Step-by-step explanation:
[tex]\frac{-x}{2}[/tex] can also be expressed as, [tex]\frac{-1}{2} x[/tex]. So all you need to do is, multiply both sides of the inequality by the reciprocal of the fraction, which is -2:
[tex]\frac{-1}{2} x[/tex] = 6
-2 · [tex]\frac{-1}{2} x[/tex] = 6 · -2
x = -12
