Question

5. (m + 1 ) - 3 . ( 2 m + 1 ) = 4. (5 - m)

Answer 1

5(m + 1) - 3(2m + 1) = 4(5 - m)
5m + 5 - 6m - 3 = 20 - 4m
-m + 2 = 20 - 4m
-m + 4m = 20 - 2
3m = 18
m = 18/3
m = 6

Answer 2

5. (m + 1 ) - 3 . ( 2 m + 1 ) = 4. (5 - m)

5m + 5 - 6m - 3 = 20 - 4m

5m - 6m + 4m= 20 - 5 + 3

-m + 4m = 15 + 3

3m = 18

m=18/3

m=6
