Question:

Looking at the equation 2x-3=21, solve for x.

Alexandra S.

The main goal of this question is to find our what x equals. The first thing we need to do is to get x on one side of the equation, all by itself. We will add 3 to each side of the equation, leaving us with 2x=24. We are close to finding x. We must then divide 2 from 2x, since we know 2x means 2 multiplied by x. 24 divided by 2 is 12. x=12. We can then plug our answer back in to make sure it is correct. 2(12)-3=21. 2 times 12 equals 24. 24 minus 3 equals 21, so our answer is correct.
