It is: 4m+5
4m+9+5m-12=42 9m=45 m=5
It can be simplified to: 4m-2n
3k+4m+2
6m + 7 - 2m + 1 = 4m + 8 If you meant: (6m + 7) - (2m + 1) = 4m + 6
4m + 327m = 331m
It simplifies to -10-4m
2n + 4m - 2n + m = 5m
-4m + 3 = -8 -4m = -8 -3 -4m = -11 4m = 11 m = 2.75
6m + 5n - 4m + 7n = 2m + 12n
It is: 9m +8 -4m +7 -5m = 15
4m^2(m + 6)
It is 4m.
4m+15=8m-5 or,4m=20 or,m=5
It is: 4m+5
