2m + 1 = 4
2m = -1 +4
2 m = 3
m = 3/2
4n - 6 = 24
4 n = 6 + 24
4 n = 30
n = 30/4
n = 15/2
9 + 10t = -45
10 t = -9 -45
10 t = -54
t = -54/10
t = -27/5
7 v - 8 = -57
7 v = +8 -57
7v = -49
v = -49/7
v = -7
2m = -1 +4
2 m = 3
m = 3/2
4n - 6 = 24
4 n = 6 + 24
4 n = 30
n = 30/4
n = 15/2
9 + 10t = -45
10 t = -9 -45
10 t = -54
t = -54/10
t = -27/5
7 v - 8 = -57
7 v = +8 -57
7v = -49
v = -49/7
v = -7
