s = 2
Explanation:[tex]-\frac{3}{2}s=-3[/tex]cross multiply:
[tex]-3s\text{ = -3(2)}[/tex]Divide both sides by -3:
[tex]\frac{-3s}{-3}=\frac{-3(2)}{-3}[/tex]NB: Division of same sign gives positive number.
[tex]\begin{gathered} s\text{ = }\frac{-6}{-3}=\text{ 2} \\ s\text{ = 2} \end{gathered}[/tex]
