9m + 9m + 3m + 3m = 24m
It is: 9m +8 -4m +7 -5m = 15
This question as written can be taken two ways: 9m + 6n - 3m + 7n = 6m + 13n, or (9m + 6n) - (3m + 7n) = 9m + 6n - 3m - 7n = 6m - n
6
15m + 4 - 9m - 32 = 6m - 28
9m
m2 + 9m + 20 = (m + 5) (m + 4)
If: 9m+2m = 33 Then: m = 3
9m-2d
4m + 9 + 5m - 12 = 42 9m -3 = 42 9m = 42 + 3 9m = 45 m = 5
6m + 20 = 9m - 4 24 = 3m m = 8
4m + 9 + 5m - 5 = 42 9m + 4 = 42 9m = 38 m = 38/9
