I need help solving this equation

Answer:
[tex]-\frac{2}{5}[/tex]
Step-by-step explanation:
you distribute the negative to y and negative 1 making it positive
add -9 to both sides that will get you to -5y = -y+ 10
you than add y to both sides giving you -4y=10 and -4 divided 10 gives you a fraction of [tex]-\frac{2}{5}[/tex]
