7m + 3 = 5m + 11
7m + 3 - 5m = 5m + 11 - 5m
2m + 3 = 11
2m + 3 - 3 = 11 - 3
2m = 8
2m/2 = 8/2
m = 4
The answer is m = 4
Insert the m value into the equation
- - - - - - - - - - - - - - - - - - - - - - - -
7m + 3 = 5m + 11
7(4) + 3 = 5(4) + 11
28 + 3 = 20 + 11
31 = 31

7m+3=5m+11
subtract 5m from both sides
2m+3=11
subtract 3 from both sides
2m=8
divide both sides by 2
m=4

7m+3=5m+11
7m=5m+11-3
7m=5m+8
7m-5m=8
2m=8
m=8/2
m=4
Proof: 7x4+3=5x4+11
28+3=20+11
31=31
