y\text{ = -4.5}

Step-by-step explanation:
-3\text{ = 15 + 4y}

Subtract 15 from both sides:


\begin{gathered} -3\text{ - 15 }=\text{ 15 - 15 + 4y} \\ -3\text{ -15 = 4y} \end{gathered}
\begin{gathered} -18\text{ = 4y} \\ \text{divide both sides y 4:} \\ (-18)/(4)=(4y)/(4) \end{gathered}
\begin{gathered} -4\text{ }(2)/(4)\text{ = y} \\ y\text{ = }-4\text{ }(1)/(2) \\ y\text{ = -4.5} \end{gathered}
