[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{a = - 8}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{3a + 15 = - 9}[/tex]
Move 15 to right hand side and change its sign
⇒[tex] \sf{3x = - 9 - 15}[/tex]
Calculate
⇒[tex] \sf{3x = - 24}[/tex]
Divide both sides by 3
⇒[tex] \sf{ \frac{3x}{3} = \frac{ - 24}{3} }[/tex]
Calculate
⇒[tex] \sf{x = - 8}[/tex]
