Work Step by Step

$\frac{x}{3}=-14+9\rightarrow$ simplify $\frac{x}{3}=-5\rightarrow$ multiply both sides by 3 $\frac{x}{3}\times3=-5\times3\rightarrow$ simplify $x=-15$ Check the solution by plugging in the value for x and determine whether the resulting equation is true. $\frac{-15}{3}=-14+9\rightarrow$ simplify $-5=-5$ This is true so the solution is correct.
