4m+9+5m-12=42 9m=45 m=5

4m+9+5m-12=42 9m=45 m=5

4m + 9 + 5m - 12 = 42 9m -3 = 42 9m = 42 + 3 9m = 45 m = 5

6m + 5n - 4m + 7n = 2m + 12n

4m + 9 + 5m - 12 = 42 Combining like terms to both sides:9m=42+12-9=>9m=45 divide both side by 9:m=5;

4m+15=8m-5 or,4m=20 or,m=5

It is [4m-1, (4m-2)/3]

4m-5 equals = -1

-4m + 3 = -8 -4m = -8 -3 -4m = -11 4m = 11 m = 2.75

simplified it equals, 9m+8

3+4m+5m=214m+5m=21-39m=18m=18/9m=2

(2m + 1) and (6m - 1)

4m + 3m = 180 7m = 180 m = 25 5/7

2n + 4m - 2n + m = 5m

405 centimeters because 4m equals 400 cm and plus 5cm equals 405cm

It simplifies to -10-4m

4m + 327m = 331m

4m = 10. 10/4=2.5. So m=2.5

4m - 37 = -28 ie 4m = -28 + 37 ie 4m = 9 so m = 2.25

4m(2m^2 + 4m + 3)

15+4m=-14m=-16 (subtract 15 from both sides to isolate variable (4m))m=-4 (divide each side to isolate variable from coefficient)

It is: 9m +8 -4m +7 -5m = 15

It is 4m.

4m^2(m + 6)

It has no solution since subtracting 4m from both sides leads to -4 = 0 which is not true.
