remember you can do anything to an equation as long as you do it to both sides
multiply both sides by (3x)(6) (basically cross multiply)
(6)(9+x)=(5)(3x)
distribute
54+6x=15x
minus 6x both sides
54=9x
divide both sides by 9
6=x
x=6

(9+x)/3x = 5/6
(9+x)/x = 15/6 (then distribute out x on bottom)
9/x + 1 = 15/6
9/x = 1.5
x = 9/1.5
x=6
