-3%2Fx=x%2F%28-3%29 Start with the given equation.


-3%28-3%29=x%2Ax Cross multiply


9=x%5E2 Multiply


x%5E2=9 Rearrange the equation


x=%22%22%2B-sqrt%289%29 Take the square root of both sides.


x=sqrt%289%29 or x=-sqrt%289%29 Break up the "plus/minus"


x=3 or x=-3 Take the square root of 9 to get 3


So the solutions are x=3 or x=-3
