# How do you solve 2( 3n + 64) = 16- n?

Dec 3, 2017

$n = - 16$

#### Explanation:

Distribute the things on the left side first.

$2 \left(3 n + 64\right) = 16 - n$

$6 n + 128 = 16 - n$

Move all variables to one side, and the whole numbers on the other. (Note: When you do something to one side, you must also do it to the other side)

$6 n + 128 - 128 + n = 16 - n + n - 128$

$6 n + n = 16 - 128$

$7 n = - 112$

Now isolate for n by dividing both sides by 7

$7 \frac{n}{7} = - \frac{112}{7}$

$n = - 16$
