-47 -2.5 = -2.5 - 1.7m - 2.3m

​

Answer 1

- 47 - 2.5 = -2.5 - 1.7m - 2.3m

m = ?

1.7m + 2.3m = - 2.5 + 47 + 2.5

4m = 47

m = 47/4

m = 11.75 ✔️

Answer 2

47/4 or 11.75 = m

Explanation:

-47 -2.5 = -2.5 - 1.7m - 2.3m

Combine like terms

-49.5 = -2.5 -4m

Add 2.5 to each side

-49.5 +2.5 = -2.5+2.5 -4m

-47 = -4m

Divide each side by -4

-47/-4 = -4m/-4

47/4 = m

11.75 = m
