# How do you solve for c: Q = 2c + 1?

Apr 5, 2018

$c = \frac{Q - 1}{2}$

Here's how I did it:

#### Explanation:

$Q = 2 c + 1$

To solve for $c$, we need to make $c$ alone. In order to do that, we have to do a couple of steps.

First, let's subtract $1$ from both sides of the equation:
$Q - 1 = 2 c$

Now, let's divide both sides by $2$:
$\frac{Q - 1}{2} = c$

So $c = \frac{Q - 1}{2}$
