# How do you solve -3(4x-2)=-21?

Jun 20, 2017

$x = \frac{9}{4}$

#### Explanation:

$- 3 \left(4 x - 2\right) = - 21$

divide by $\left(- 3\right)$ to both sides
$\frac{- 3 \left(4 x - 2\right)}{-} 3 = - \frac{21}{-} 3$
$4 x - 2 = 7$

add $2$ to both sides
$4 x - 2 + 2 = 7 + 2$
$4 x = 9$

divide $4$ to both sides
$\frac{4 x}{4} = \frac{9}{4}$
$x = \frac{9}{4}$
