3m + 15 = 45 3m = 30 m = 10
If 3m - 7 = 8, then m = 5
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.

5m = 2m - 153m = -15m = -15/3m = -5
3m + 15 = 45 3m = 30 m = 10
If 3m - 7 = 8, then m = 5
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.
6m + 5 = 3m - 4Subtract 3m from each side:3m + 5 = -4Subtract 5 from each side:3m = -9Divide each side by 3:m = -3
3m + 7 = 5 Subtract 7 from both sides: 3m = -2 Divide both sides by 3: m = -2/3
It is an equation and the value of m is -6
3m+2=17 First, subtract 2 to get m on one side. 3m+2-2=17-2 3m=15 Divide by 3 to get m by itself. 3m/3=15/3 m=5 m equals 5.

4m + 3m = 180 7m = 180 m = 25 5/7
5m = 2m - 153m = -15m = -15/3m = -5
3m-5 = 7-21 3m = 7-21+5 3m = -9 m = -3
It is: 4m+5
