What is t-8 equals 15?

Answer 1

t - 8 = 15

To solve for t, we want to get t by itself on one side of the equal sign. So if we are subtracting 8 from t, we need to add 8 to get rid of it, but what we do on one side of equal sign, we need to do to the other side.

So t - 8 + 8 = 15 + 8

So t = 15 + 8

So t = 23
