That three on the left side is under all of x+3-(3x) right?? so
At that point when you multiply both sides by three don't you just get rid of the three in the denominator so the equation at this point would be
x+3-3x=3y
then combine the x and -3x and get -2x+3=2y and then x =-(2y-3)/2 ?? so question 3 isn't the center of the universe??? can't be i must of done something wrong
