 $\bold{Hello!}\\\bold{Your~Answer~Is~Below!}$

______________________________

 $\bold{Solution~Steps:}$

$1.)~Combine~8s~and~-4s:$

• $\bold{8s+(-4s)=4s}$

$2.)~Subtract~7s~from~both~sides:$

• $\bold{7s-7s=Cancels~out}$

• $\bold{4s-7s=-3s}$

$3.)~Subtract~15~from~both~sides:$

• $\bold{15-15=Cancels~out}$

• $\bold{6-15=-9}$

$4.)~Divide~both~sides~by~-3:$

• $\bold{-3s}$ ÷ $\bold{-3s=Cancels~out}$

• $\bold{-9}$ ÷ $\bold{-3=3}$

• $\bold{When~there~is~2~negatives~being~divided,~the~quotient~is~always~positive.}$
