Solution

[tex]12=-\frac{2}{5}y[/tex]

Step 1: Simplify the expression

[tex]\begin{gathered} 12=-\frac{2}{5}y \\ \text{cross multiply} \\ 12(5)=-2y \\ 60=-2y \end{gathered}[/tex]

Step 2: Divide the both side by -2

[tex]\begin{gathered} 60=-2y \\ \frac{60}{-2}=-\frac{2y}{-2} \\ y=-30 \end{gathered}[/tex]

Therefore the correct value of y = - 30
