Step 1.1

Factor $2$ out of $10$ .

$a = \frac{2 (5) - 2}{4}$

Step 1.2

Factor $2$ out of $- 2$ .

$a = \frac{2 \cdot 5 + 2 \cdot - 1}{4}$

Step 1.3

Factor $2$ out of $2 \cdot 5 + 2 \cdot - 1$ .

$a = \frac{2 \cdot (5 - 1)}{4}$

Step 1.4

Cancel the common factors.

Step 1.4.1

Factor $2$ out of $4$ .

$a = \frac{2 \cdot (5 - 1)}{2 (2)}$

Step 1.4.2

Cancel the common factor.

$a = \frac{2 \cdot (5 - 1)}{2 \cdot 2}$

Step 1.4.3

Rewrite the expression.

$a = \frac{5 - 1}{2}$

$a = \frac{5 - 1}{2}$

$a = \frac{5 - 1}{2}$

Step 2

Simplify the expression.
