Answer :
[tex]\begin{gathered} \frac{x}{28}=-6 \\ \text{Solving for x:} \\ \text{Multiply both sides by 28:} \\ 28\cdot(\frac{x}{28})=-6\cdot28 \\ x=-168 \end{gathered}[/tex][tex]\begin{gathered} \frac{x}{28}\cdot28=x\cdot\frac{28}{28} \\ \frac{28}{28}=1 \\ so\colon \\ x\cdot1=x \end{gathered}[/tex]
