# How do you solve 16-2.4x=-8?

Mar 16, 2017

$x = 10$

#### Explanation:

$16 - 2.4 x = - 8$

Move $- 8$ to the left and $- 2.4 x$ to the right.
$16 + 8 = 2.4 x$
$24 = 2.4 x$
$x = 10$

$x = 10$

#### Explanation:

$16 - 2.4 x = - 8$

$- 2.4 x = - 8 - 16$

$- 2.4 x = - 24$

multiply L.H.S. and R.H.S. by color(red)(-1

$2.4 x = 24$

$x = {\cancel{24}}^{\textcolor{red}{10}} / {\cancel{2.4}}^{\textcolor{red}{1}}$

$x = 10$

substitute color(red)(x=10

$16 - 2.4 \left(\textcolor{red}{10}\right) = - 8$

$16 - 24 = - 8$

$- 8 = - 8$
