## Step 1. Given information

In the following exercise, solve each equation using the Subtraction and Addition Properties of Equality.
$a+\frac{2}{5}=\frac{4}{5}$

## Step 2. Explanation

$\begin{array}{l}⇒a+\frac{2}{5}=\frac{4}{5}\\ \text{Subtract}\frac{2}{5}\text{from each sides}\\ ⇒a+\frac{2}{5}-\frac{2}{5}=\frac{4}{5}\text{-}\frac{2}{5}\text{}\\ ⇒a=\frac{4}{5}\text{-}\frac{2}{5}\text{}\\ \text{Taking LCD to solve right side of the equation}\\ ⇒a=\frac{4-2}{5}\text{}\\ ⇒a=\frac{2}{5}\end{array}$ ### Want to see more solutions like these?
