Answer:
The solution to the equation is;
[tex]y=-4.5[/tex]Explanation:
Given the equation;
[tex]-3=15+4y[/tex]firstly let's subtract 15 from both sides;
[tex]\begin{gathered} -3-15=15-15+4y \\ -18=4y \end{gathered}[/tex]then we can now divide both sides by 4;
[tex]\begin{gathered} \frac{-18}{4}=\frac{4y}{4} \\ -4.5=y \\ y=-4.5 \end{gathered}[/tex]Therefore, the solution to the equation is;
[tex]y=-4.5[/tex]
