Question

7x + x + 11 = 11x - 3 - x procedimiento​

Answer 1

$7x + x + 11 = 11x - 3 - x \\ 7x + x - 11x + x = - 3 - 11 \\ 9x - 11x = - 14 \\ - 2x = - 14 \\ x = \frac{ - 14}{ - 2} \\ x = 7$

Answer 2

Respuesta:

X=7

Explicación paso a paso:

7x + x + 11 = 11x - 3 - x

8x +11 = 10x-3

11+3 = 10x-8x

14 = 2x

14/2 = x

X=7
