Answer 1

Respuesta:

$x=- \frac{16}{51}$

Explicación paso a paso:

$-5w + 8 (1+7w)=-8\\\\-5w +8 + 56 w = -8\\\\-5 w + 56 w = -8 -8\\\\51 w = - 16\\\\w = -\frac{16}{51}$

Comprobación:

$- 5 (\frac{-16}{51}) + 8 ( 1 + 7 (\frac{-16}{51} )=-8\\\\\frac{80}{51} + 8 (1 -\frac{112}{51} )= -8 \\\\\frac{80}{51} + 8 (\frac{51 - 112}{51} )= -8\\\\\frac{80}{51} + 8(-\frac{61}{51})=-8\\\\\frac{80}{51} -\frac{488}{51} = -8\\\\\frac{80 - 488}{51}= -8\\\\\frac{-408}{51}=-8\\\\-8=-8$
