X=8
B-7.5=3.X-1
X=0
X=12
X=35
_CON EXPLICACION_

Answer 1

Respuesta:

4x + 2 = 34

4x = 34 - 2

4x = 32

x = 32/4

x = 8

Comprobación

4 (8) + 2 = 34

32 + 2 = 34

34 = 34

Explicación paso a paso:

- 7 . 5 = 3x -1

-35 = 3x -1

- 3x = 35 -1

-3x = 34

x = 34/-3

Comprobación

- 7 . 5 = 3 (34/-3) - 1

- 35 = -34 -1

-35 = -35
