Question

1А. 2а - 9 ба + 15 solving equation with variable on both sides

Answer 1

Answer:

a = -3

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;

$\begin{gathered} \frac{-8a}{-8}=\frac{24}{-8} \\ a\text{ = -3} \end{gathered}$

Hence the solution is a = -3
