X=18. You can reason this out by putting the question into a sentence. "What number is 6 one third of?" Or "what number is 3 times 6?" Algebraically, the problem breaks down to x/3 = 6 . . . x=3*6 . . . x-18
This is a 1-step equation. Here's how to solve it. (1/3)x = 6 Get x alone on the left side. To do this,remove 1/3 by doing the opposite of 1/3 times. The opposite of times is to divide by 1/3. Also divide right side by 1/3 since you have to do the same thing to both sides, to keep things equal. (1/3)x / (1/3) = 6/(1/3) x = 6/1 times 3/1 x = 18. ANSWER Hope this helps!
