Answer:
a = ![\frac{c+d}{b}](https://tex.z-dn.net/?f=%5Cfrac%7Bc%2Bd%7D%7Bb%7D)
Step-by-step explanation:
First, you want to add d on both sides.
ab-d = c
<u>+d +d</u>
ab = c+d
Now, divide b on both sides.
ab = c+d
<u>/b /b</u>
a = ![\frac{c+d}{b}](https://tex.z-dn.net/?f=%5Cfrac%7Bc%2Bd%7D%7Bb%7D)
I hope this helps; have a great day c:
