# How do you solve 8- 6( 1- 7b ) = - 82?

Sep 24, 2016

Multiply first then isolate $b$.

#### Explanation:

Multiply $8 - 6$ and $\left(1 - 7 b\right)$. You must get $8 - 56 b - 6 + 42 b$.

Simplify. This will then be: $2 - 14 b$.

It will look like: $2 - 14 b = - 82$

Isolate $b$

$- 14 b = - 82 - 2$

Divide by $- 14$ both sides.

Then:

$b = - \frac{84}{-} 14$

And $b = 6$.
