Question 56632
Expanding the equation we get {{{3*x+3*6=5*x-5*4}}} which simplifies to {{{3x+18=5x-20}}}.  Now add 20 to both sides to get {{{3x+18+20=5x-20+20}}} which reduces to {{{3x+38=5x}}}.  Now substract 3x from both sides {{{3x-3x+38=5x-3x}}} and that reduces to {{{38=2x}}}.  Dividing both sides by 38, we get x=19.
