*The answer should have a positive sign.*
Explanation:
First, you do is switch sides.
![(m)/(2)-7=2](https://img.qammunity.org/2020/formulas/mathematics/high-school/h1p95w5kc2mpsdemdy5rjs4j66v5xacdn1.png)
Then, you add by 7 from both sides.
![(m)/(2)-7+7=2+7](https://img.qammunity.org/2020/formulas/mathematics/high-school/kd2kdjynpkzjl74utih7dzwjavgwi2zht7.png)
Add numbers from left to right.
![2+7=9](https://img.qammunity.org/2020/formulas/mathematics/high-school/w63el68ll0ujy44cskhk2msae7284n6yqj.png)
![(m)/(2)=9](https://img.qammunity.org/2020/formulas/mathematics/high-school/5qkxlomrrlpmy9izitr8tpl7ehfmdr19fl.png)
Multiply by 2 from both sides.
![(2m)/(2)=9*2](https://img.qammunity.org/2020/formulas/mathematics/high-school/fquy8ed6z7ls6wisigjmvzlf9bhbtbmg2n.png)
Finally, multiply numbers from left to right.
![9*2=18](https://img.qammunity.org/2020/formulas/mathematics/high-school/ptfl115d0csfdy1top5sxkhhl3oee0g3jr.png)
m=18 is the correct answer.
I hope this helps you!
Have a wonderful day! :)
