Question

Solve the equation 15-x = 24. Round your answer to the nearest hundredth

Answer 1

All you have to do to solve this question is to swap the -x and 24. It is of utmost importance that you do NOT forget to switch the signs of the moving values. You should end up with something looking a little bit like this.
15-x = 24
15 - 24 = x
-9=x

Answer 2

The answer should be -9. It's the only way to get a high number from subtraction (a double negative)
