X-3/18=12/9 find proportion

Hi friend!

Firstly, you have to simplify both sides of your equation

X + -1/6 = 4/3

Secondly, you have to add by 1/6 on each of your sides that you're working with

X + -1/6 + 1/6 = 4/3 + 1/6

CANCEL: -1/6 + 1/6
because it gives you the result of 0
KEEP: 4/3 + 1/6
because it gives you the answer for x
therefor the answer is x = 3/2
