Answer :

5 (y-6) = 3 (y-4)
5y - 30 = 3y - 12
2y -30 = -12
2y = 18
y = 9
5 (y - 6) = 3 (y - 4)         :First, distribute on both sides.

5y - 30 = 3y - 12          
:Then, add the 30 over to the 12.
     
+30         +30

5y = 3y + 18                 :Next, subtract the 3y over to the 5y.
-3y   -3y

(2y = 18)  ÷ 2                :Then, divide the whole equation by 2

Your final answer is:
y = 9
