Question 194428
{{{(-3x)/x = x/(-3)}}} Start with the given equation. Take note that we must make the restriction {{{x<>0}}} (to avoid division by zero)



{{{-3 = -x/3}}} Reduce. 



{{{-3(3) = -x}}} Multiply both sides by 3.



{{{-9 = -x}}} Multiply



{{{-x = -9}}} Rearrange the equation



{{{x = 9}}} Divide both sides by -1 to isolate x.



So the solution is {{{x=9}}}
