# How do you solve 3x +9-7x = 2(x 6)?

Dec 27, 2017

$x = \frac{9}{16}$

#### Explanation:

We have that:

$3 x + 9 - 7 x = 2 \left(x 6\right)$

First, gather the like terms on the left side and multiply out the bracket on the right side:

$- 4 x + 9 = 12 x$

Subtract by $12 x$:

$- 16 x + 9 = 0$

Subtract by $9$

$- 16 x = - 9$

Now divide by $- 16$ to get:

$x = \frac{9}{16}$
