Given:
8r - 5q = 3
Make q the subject.
First step:
Subtract 8r from both sides of the equation:
8r - 8r - 5q = 3
-5q = 3 - 8r
Second Step:
Divide both sides by -5
[tex]\begin{gathered} \frac{-5q}{-5}=\text{ }\frac{3-8r}{-5} \\ \\ q\text{ = }\frac{3-8r}{-5} \end{gathered}[/tex]ANSWER:
[tex]q\text{ = }\frac{3-8r}{-5}[/tex]
