Question 54728
The equation expands to {{{6*6-6x=3x}}}, which reduces to {{{36-6x=3x}}}.  Adding 6x to both sides yields {{{36=9x}}} and dividing both sides by 9 gives us {{4=x}}}.  Substituting that value into the original equation gives {{{6(6-4)=3*4}}}, which expands to {{{6*2=12}}} and that reduces to {{{12=12}}}.  Because 12=12 is a true statement, that means our answer of x=4 is correct!
