In order to find which solutions have m = 4, solve m for each of one

Solution:

a)

13 = 9 + m

m = 13 - 9

m = 4

b)

7 - m = 3

m = 7 - 3

m = 4 

c)

15 = 11m

m = 11/15

d)

5 = m + 2

m = 5 - 2

m = 3

e) 

20/m =5

20 = 5m

m =4

The solutions that have m = 4, are (13 = 9+m), (7 - m = 3), and( 20/m =5).
