-5m-3+4 = 11 -5m = 11+3-4 -5m = 10 m = -2
5m - 5 + 2 = 1 Therefore, 5m - 3 = 1 5m = 4 m = 4/5 m = 0.8
-7m - 3m + 5m = -5m
m = 4
Of course: 25m2 - 20m + 4 = (5m - 2)2.
-5m-3+4 = 11 -5m = 11+3-4 -5m = 10 m = -2
5m - 6 + m + 10 = 6m + 4
5m - 5 + 2 = 1 Therefore, 5m - 3 = 1 5m = 4 m = 4/5 m = 0.8
5m-5n+5m+5n When simplified: 10m
-7m - 3m + 5m = -5m
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
4m + 9 + 5m - 5 = 42 9m + 4 = 42 9m = 38 m = 38/9
m = 4
5m-3x+3m+2x 2m-x
5m-13n-n+4m= (5+4)m+(-13-1)n= 9m-14n
It is simply: 5m+2
Of course: 25m2 - 20m + 4 = (5m - 2)2.
