Since you are solving for a, you want to have a on one side of the equation and the other terms on another side of the equation. It would be easiest to have all the terms with a on the left side of the equation, so that is what we will do.
Subtract 9a from both sides to get a on the left side of the equation.
5 + 5a = -5
Subtract 5 from both sides of the equation to isolate the term with a.
5a = -10
Divide both sides of the equation by 5 to solve for a.
a = -2
5 + 14a = 9a - 5
-9a -9a
5 + 5a = -5
-5 -5
5a = -10
[tex]\frac{5a}{5} = \frac{-10}{5}[/tex]
a = -2
Answer: a = -2
