# How do you solve -5=6x+3+7x?

Jan 11, 2017

$x = \frac{- 8}{13}$

#### Explanation:

Given -

$- 5 = 6 x + 3 + 7 x$

Let us rewrite by taking the unknown to the left -

$6 x + 3 + 7 x = - 5$

Simplify

$13 x + 3 = - 5$

Add $- 3$ to both sides

$13 x \cancel{+ 3} \cancel{- 3} = - 5 - 3$

Simplify -

$13 x = - 8$

Multiply both sides with $\frac{1}{13}$

$\cancel{13} x \times \frac{1}{\cancel{13}} = - 8 \times \frac{1}{13}$

$x = \frac{- 8}{13}$
