First, distribute.
[tex]3y - 27 = 7y + 2[/tex]
Subtract the 3y from both sides.
[tex] - 27 = 4y + 2[/tex]
Subtract 2 from both sides.
[tex] - 29 = 4y[/tex]
To get the variable by itself, divide by 4.
[tex] - \frac{29}{4} = y[/tex]
Your answer is:
[tex]y = - \frac{29}{4} [/tex]

Step-by-step explanation:

I'm really really sorry if I'm wrong...

3(y-9)=5y+2

3y - 27 = 5y + 2

    + 27        + 27

3y = 5y + 29

-5y  -5y

-2y = 29

-2       -2

y = -14.5
