m = -1
5m - 5 + 2 = 1 Therefore, 5m - 3 = 1 5m = 4 m = 4/5 m = 0.8
5m-7m = 12 -2m = 12 -2m/-2 = 12/-2 m = -6
-5m-3+4 = 11 -5m = 11+3-4 -5m = 10 m = -2
m2 - 5m - 14 = 0(m - 7) (m + 2) = 0The equation is true ifm = 7orm = -2
m = -1
5m - 5 + 2 = 1 Therefore, 5m - 3 = 1 5m = 4 m = 4/5 m = 0.8
5m-7m = 12 -2m = 12 -2m/-2 = 12/-2 m = -6
-5m-3+4 = 11 -5m = 11+3-4 -5m = 10 m = -2
5m=40/5=/5m=8
m2 - 5m - 14 = 0(m - 7) (m + 2) = 0The equation is true ifm = 7orm = -2
m = 8
m = 4
m = 4
2 - 7n = 6therefore 7n = 2 - 6 = -4 and so n = -4/7 Then 5m + 7n = 6.4 becomes 5m - 4 = 6.4 so that 5m = 10.4 and then m = 10.4/5 = 2.08
40
Assuming -5m=11:Divide both sides by -5: m= -11/5And you have what m equals.
