Leroy Cunningham · Answer 1

-4+m=7 next do 13-m=2 m equals 11 it all equals 14

Craig Zamora · Answer 2

The answer is m = 7.

1. (13-m=2 (m-4) Regroup terms

2. Expand (13-m=2m - 8)

3. Add m to both sides (13=2m-8 + m)

4. Simplify (2m-8+m to 3m-8)

5. add 8 to both sides (13 + 8 = 3m)

6. Simplify 13+8 to 21

7. Divide both sides by 33 (21/3 = m)

8. simplify 21/3 to 7 (7 = m)

9. switch sides (finally m = 7)
