Question

Describe and correct the error in solving the equation

Answer 1

The student is very close to the correct steps.

However, they forgot about a negative sign. They should have multiplied both sides by -3.

The answer should be m = 12

Here's how we can check the answer.

`-(m)/(3) = -4\\\\-(12)/(3) = -4\\\\-4 = -4 \ \ \ \ \checkmark`

We end up with the same thing on both sides, so the answer m = 12 is confirmed.
