30 is the answer.

How you solve it:

You take 3X and divide it by 3, then do the same thing to 90 and you will get 30.

3x = 90

You’re trying to solve for x, so since x is being multiplied by 3, we divide both sides by 3 to isolate x.

3x/3 = 90/3
x = 90/3
x = 30

Now to check your work...
3(30) = 90
90 = 90


The answer is x = 30
