Answer 2

First start this by SUBTRACTing 7 on both sides of the equation since you are originally adding 7.

3m + 7 - 7 = 28 - 7

3m = 28 - 7

What' 28 - 7?

Answer 3

oops sorry and its 21

Answer 4

It's fine! :) And right

3m = 21

What do you think we do now? As we can see we are multiplying 3. We have to do the oppisite to both sides, right? So do we multiply or divide 3?

Answer 5

multiply?

Answer 6

No :P We do the oppisite, so we divide.

3m = 21

3m/3 = 21/3

m = 21/3

What's 21/3?

Answer 7

7.

Answer 8

Right! so m = 7
