Question

Resuelvan las siguientes ecuaciones:

7m + 4 = 4m + 24 - 2m:

-5m = 9m + 14:

-7n = 9n - 16

-2x = 7x - 18

-6c + 9 = -4c -3

1/2x + 8 = x + 10

1/3x + 8 = x + 10

3x + 1 = x + 2

Answer 1

7m+4= 4m +24-2m
7m= 2m +20
5m = 20
m=20/5
m= 4


-5m =9m +14
-14m = 14
m= 14/-14
m= -1

-7n = 9n -16
-16 n= -16
n= -16/-16
n= 1

-2x = 7x -18
-9x = -18
x= 2

-2c = -12
c= 6
