Step-by-step explanation:
Use the Distributive Property in order to solve.
Distributive Example:[tex]a(b+c)=ab+ac[/tex]
Using the property into the equation:
[tex]3(3y-9)=3(3y)-3(9)=9y-27[/tex]
[tex]9y-27=0[/tex]
Add 27 to both sides:
[tex]9y=27[/tex]
Divide each side by 9:
[tex]y=3[/tex]
b is correct.
