# How do you solve 4d + 2(d - 1) = 22?

Mar 20, 2018

$d = 4$

#### Explanation:

We can start by distributing the $2$ to the terms in parenthesis. We get:

$4 d + 2 d - 2 = 22$

We can further simplify the terms on the left to get:

$6 d - 2 = 22$

Adding $2$ to both sides, we have:

$6 d = 24$

Finally, we can divide both sides by $6$ to get:

$d = 4$
