You have the equation -4y=28
To solve this equation you need to clear the value of the unknown variable y, meaning, you have to simplfy the equation until you reach y=
For this, since y is multiplied by -4 you have to divide it by -4 to leave y alone, and what you do in one side of the equation must be done to the other side to keep the equality:
[tex]\begin{gathered} -4y=28 \\ \frac{-4y}{-4}=\frac{28}{-4} \\ y=-7 \end{gathered}[/tex]The value of y=-7
