DOY CORONITA

1) 2m +8 = 12

2) 4x -7= 13

3) -5x+8 = -2

4) 3y -7 = 5

5) 9m +2 =92

Answer 1

Respuesta:

Holaa!

1) 2m + 8 = 12

2m = 12 - 8

2m = 4

m = 4/2

m = 2

2) 4x - 7 = 13

     4x = 13 + 7

     4x = 20

      x = 20/4

      x = 5

3) -5x + 8 = -2

    -5x = -2 -8

    -5x = -10

     x = -10/-5

x = 2

4) 3y - 7 = 5

    3y = 5 + 7

3y = 12

y = 12/3

y = 4

5) 9m + 2 = 92

9m = 92 - 2

9m = 90

m = 90/9

m = 10
