4m+15=8m-5 or,4m=20 or,m=5
3+4m+5m=214m+5m=21-39m=18m=18/9m=2
It has no solution since subtracting 4m from both sides leads to -4 = 0 which is not true.
4m + 327m = 331m
It simplifies to -10-4m
4m+15=8m-5 or,4m=20 or,m=5
3+4m+5m=214m+5m=21-39m=18m=18/9m=2
3m plus 19. Change it if I am wrong!
4m + 12 = 604m + 12 -12 = 60 -12 (1st subtract 12 from both sides)4m = 484m/4 = 48/4 (now divide both sides by 4 to solve for m)m = 12
15+4m=-14m=-16 (subtract 15 from both sides to isolate variable (4m))m=-4 (divide each side to isolate variable from coefficient)
(4+9)+(5−1242) = −1224 (I assume m stands for metres?)
It has no solution since subtracting 4m from both sides leads to -4 = 0 which is not true.
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
