Answer 1

Respuesta:

X= -1/7

Explicación paso a paso:

Answer 2

Respuesta:

4x + (2x - 1) + x = 2x - (2 + x) - x

4x + 2x - 1 + x = 2x - (2 + x) - x

Agrupamos términos

4x + 2x + x - 1 = 2x - (2 + x) - x

4x + 2x + x = 7x

7x - 1 = 2x - x - (x + 2)

2x - x = x

7x - 1 = x - (x + 2)

Resolver:

x - (x + 2) = -2

7x - 1 = -2

7x = -2 + 1

7x = -1

Solución

$\frac{-1}{7}=-\frac{1}{7}$

$\boxed{x=-\frac{1}{7}}$
