Step-by-step answer

P Answered by Specialist

x = -8

Step-by-step explanation:

$-\frac{1}{3}\left(6x+18\right)=10$

$\mathrm{Multiply\:both\:sides\:by\:}-3$

$\left(-\frac{1}{3}\left(6x+18\right)\right)\left(-3\right)=10\left(-3\right)$

$\mathrm{Simplify}$

6x+18=-30

$\mathrm{Subtract\:}18\mathrm{\:from\:both\:sides}$

6x+18-18=-30-18

$\mathrm{Simplify}$

6x=-48

$\mathrm{Divide\:both\:sides\:by\:}6$

$\frac{6x}{6}=\frac{-48}{6}$

$\mathrm{Simplify}$

x=-8
