X= 3y-9 solve for y, now i need a refresher on this mind me?

Is this all? You can’t obtain a number value for y, but you can obtain that y equals (9+X)/3

Step-by-step explanation:

X=3y-9

Distribute the right hand side.

3y-9=3(y-3)

Therefore,

X=3(y-3)

Divide both sides by 3

(X/3)=y-3

Add 3 to both sides

(X/3)+3=y

Simplify

(X/3)+(9/3)=y

y=(9+X)/3

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?
