The goal is to get x by itself. So you have 3/4x=1464. First you would multiply by 4 on both sides to get rid of the fraction. 1464x4 is 5,856
So what you're left with is 3x=5,856, so you divide on both sides by 3 to get x by itself and end up with the answer x=1952.
Another way to do this is if you understand how fractions work, 3/4 is equivalent to .75 so think of it as .75x=1464 and divide by .75 on both sides to get 1952. Either way works and either way x=1,952
