2 times what equals 90?

2 times what equals 90? In other words, what do you multiply by 2 to get 90? If "x" is "what" in the sentence, "2 times what equals 90?", then the equation to solve the problem is as follows:

2 • x = 90

Which can be written as:

2x = 90

To solve the equation above, we need to remove the 2 on the left side to make the x alone. To do that, we divide both sides by 2.

2x/2 = 90/2

2x/2 is x and 90/2 is 45 which means our equation will look like this:

x = 45

Thus, the answer to "2 times what equals 90?" is 45.

To double-check our work, multiply 45 by 2 to see that it equals 90. (Note that our answer on this page is rounded to 4 digits if necessary.)
