Answer 2

- 4x + 13 = 6x - 7

7 + 13 = 6x + 4x

20 = 10x

20/10 = x

2 = x

COMPROBACIÓN =

- 4x + 13 = 6x - 7

- 4(2) + 13 = 6(2) - 7

- 8 + 13 = 12 - 7

5 = 5

3x - 8 = x + 4

3x - x = 4 + 8

2x = 12

x = 12 / 2

x = 6

COMPROBACIÓN =

3x - 8 = x + 4

3(6) - 8 = x + 4

18 - 8 = 6 + 4

10 = 10

4x + 20 = 45 - x

4x + x = 45 - 20

5x = 25

x = 25 / 5

x = 5

COMPROBACIÓN =

4x + 20 = 45 - x

4(5) + 20 = 45 - 5

20 + 20 = 40

40 = 40

-7m - 5 = 5m + 1

-7m - 5m = 1 + 5

- 12m = 6

m = 6 / - 12

m = - 1/2

COMPROBACIÓN =

- 7m - 5 = 5m + 1

- 7(-1/2) - 5 = 5(-1/2) + 1

7/2 - 10/2 = - 5/2 + 2/2

- 3/2 = - 3/2

Saludossss!!!!, dudas aquí sigooooooo!!!!.
