Answer 1

Respuesta:

5x + 6 = 21

5x = 21 - 6

x = 15 / 5

x = 3

-2x + 8 = - 2

-2x = -2 - 8

x = -10 / - 2

x = 5

6x + 2 = -16

6x = - 16 - 2

x = -18 / 6

x = - 3

2x + 4 = 6

2x = 6 - 4

x = 2 / 2

x = 1

-4x - 6 = - 2

-4x = -2 + 6

-4x = 4

x = 4 / -4

x = - 1

x + 4 = 10

x = 10 - 4

x = 6

- x + 1= - 8

- x = - 8 - 1

- x = - 9

x - 5 = 5

x = 5 - 5

x = 0

- 4 + 2x = 0

2x = 0 + 4

x = 4 / 2

x = 2

2x + 4 =0

2x = 0 - 4

2x = - 4

x = - 4 / 2

x = - 2
