Answer

$x=-48$

Work Step by Step

$\frac{x}{-2}=5^2-|-10|-(-9)\rightarrow$ absolute value of -10 is 10 $\frac{x}{-2}=5^2-10-(-9)\rightarrow$ simplify $\frac{x}{-2}=25-10-(-9)\rightarrow$ simplify $\frac{x}{-2}=24\rightarrow$ multiply both sides by -2 $\frac{x}{-2}\times-2=24\times-2\rightarrow$ simplify $x=-48$
