<em>*To solve for a specified variable, you need to isolate that variable onto one side.</em>

Firstly, subtract 5r on both sides: $2p=q-5r$

Lastly, divide both sides by 2 and <u>your answer will be $p=\frac{1}{2}q-\frac{5}{2}r$ </u>

First, subtract z on both sides of the equation: $-10-z=xy$

Next, divide both sides by y and <u>your answer will be $\frac{-10-z}{y}=x$ </u>

Firstly, multiply both sides by b: $a=cb$

Next, divide both sides by c and <u>your answer will be $\frac{a}{c}=b$ </u>
