# How do you solve for b in 2a+4b=d?

Aug 2, 2018

$b = - \frac{a}{2} + \frac{d}{4}$

#### Explanation:

Let's begin to isolate the $b$ term by subtracting $2 a$ from both sides. We now have

$4 b = - 2 a + d$

Lastly, we can divide both sides by $4$ to get

$b = - \frac{a}{2} + \frac{d}{4}$

Hope this helps!
