Make sure you have a common denominator first so it would be 9/16x = 12/16 (you multiply 3/4 by 4/4 to get the bottom to equal 16) Afterwards, times 16 on each side to get rid of it. Then you get 9x = 12 By dividing 9 on each side to isolate the variable, you would get x = 12/9 Afterwards, simplify it. x = 4/3
