Question

1) │3x - 4│= 23

2) │2x + 1│ + 3 = 8


4) │x - 6│ = │5x + 8│

Answer 1

Respuesta:

1).

3x - 4 = 23

3x = 23 + 4

3x = 27

3x : 3 = 27 : 3

X = 9

2).

| 2x + 1 | + 3 = 8

2x + 1 + 3

2x + 4 = 8

2x = 8 - 4

2x = 4

2x : 2 = 4 : 2

X = 2

3).

x - 6 = 5x + 8

x - 5x = 8 + 6

-4x = 14

-4x : -4 = 14 : -4

X = - 7
