Hey there!☺
[tex]Answer:\boxed{y=-40}[/tex]
[tex]Explanation:[/tex]
[tex]\frac{y}{-4}+5=15[/tex]
In our first step, we will simplify both sides of the equation:
[tex]\frac{x-1}{4}y+5=15[/tex]
Now we will subtract 5 from both sides:
[tex]\frac{-1}{4}y+5-5=15-5\\\frac{-1}{4}y=10[/tex]
Now in our last step, we will multiply both sides by 4/(-1):
[tex](\frac{4}{-1})\times(\frac{-1}{4}y)=(\frac{4}{-1})*(10)\\ y=-40[/tex]
y=-40 is your answer.
Hope this helps!☺
