# How do you solve 2(x-1) + 3= x -3(x+1)?

Mar 14, 2017

$x = - 1$

#### Explanation:

$2 \left(x - 1\right) + 3 = x - 3 \left(x + 1\right)$

expand the equation in the parentheses

$2 x - 2 + 3 = x - 3 x - 3$

#2 x + 1 = -2 x -3

add $2 x$ to both sides,
$4 x + 1 = - 3$

minus $1$ to both sides,
$4 x = - 4$

divide $4$ to both sides
$x = - 1$
