5m = 2m - 15
3m = -15
m = -15/3
m = -5

To solve the equation 5m + 3 = 3m + 9, you need to isolate the variable m. Start by subtracting 3m from both sides to get 2m + 3 = 9. Then, subtract 3 from both sides to get 2m = 6. Finally, divide by 2 to find m = 3.
5m + 7 - 2m - 1 = 3m + 6
-3m = 5m+8 -3m-5m = 8 -8m = 8 m = -1
2m x 5m = 10 sq. m.
