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.

3m + 11n = 3
3m + 9 = 36subtract 9 from both sides3m = 27divide both sides by 3m = 27/3 = 9
If -3m+5=-22, then you do this math: -22-5= -3m. -22-5=-27, so if you take the negative signs away from -27 and -3m, divide 27 by 3 to get 9, therefore m=9.
4m + 9 + 5m - 12 = 42 9m -3 = 42 9m = 42 + 3 9m = 45 m = 5
0.5 + 4m = 3m - 2.5 (subtract 0.5 and 3m to both sides)0.5 - 0.5 + 4m - 3m = 3m - 3m -0.5 -2.5m = -3Check:0.5 + 4m = 3m - 2.5 (substitute -3 for m)0.5 + 4(-3) =? 3(-3) - 2.50.5 - 12 =? -9 -2.5-11.5 = -11.5 TrueThus, for m = -3 the above equation is a true statement.
