Step 3.4.1

Add $10$ to both sides of the equation.

$p = \frac{15}{2} + 10$

Step 3.4.2

To write $10$ as a fraction with a common denominator, multiply by $\frac{2}{2}$ .

$p = \frac{15}{2} + 10 \cdot \frac{2}{2}$

Step 3.4.3

Combine $10$ and $\frac{2}{2}$ .

$p = \frac{15}{2} + \frac{10 \cdot 2}{2}$

Step 3.4.4

Combine the numerators over the common denominator.

$p = \frac{15 + 10 \cdot 2}{2}$

Step 3.4.5

Simplify the numerator.
