As given by the question
There are given that the equation:
[tex]-5y-9=-(y-1)[/tex]Now,
Solve the above equation
So,
[tex]\begin{gathered} -5y-9=-(y-1) \\ -5y-9=-y+1 \\ -5y-9+y-1=0 \\ -4y-10=0 \end{gathered}[/tex]Then,
[tex]\begin{gathered} -4y-10=0 \\ -4y=10 \\ y=\frac{10}{-4} \\ y=-2.5 \end{gathered}[/tex]Hence, the value of y is -2.5.
