You can put this solution on YOUR website! 5m + 4 = 8 - 7m (given)
Add 7m to both sides to collect like terms
12m + 4 = 8 (like terms collected)
Subtract 4 from both sides to collect like terms
12m = 4 (like terms collected)
Divide by 12 to solve for m
m = 4/12 (solved for m)
Simplify 4/12
m = 1/3 (simplified)
