If x*3=64, what is the value of x?

21.3 repeating

Step-by-step explanation:

To solve for x, you need to do the inverse operation of multiplication.

So the inverse of multiplication is division.

So divide 3 by itself to isolate x, and whatever you do to one side you have to do to the other so:

3/3 = 1

64/3 = 21.3 repeating

x = 21.3 repeating

x = 21.3 repeating. so put the - on top of the 3 if you're writing it down
