Answer:

a = -3

Step-by-step explanation:

Given the equation;


-2a\text{ - 9 = 6a+15}

Collect the like terms;


\begin{gathered} -2a-6a\text{ = 15 + 9} \\ -8a\text{ = 24} \end{gathered}

Divide bith sides by -8;


\begin{gathered} (-8a)/(-8)=(24)/(-8) \\ a\text{ = -3} \end{gathered}

Hence the solution is a = -3
