How do you solve #4/(9y-6)=2#?
1 Answer
Step by step explanation is given blow
Explanation:
Think of this as a proportion
#4/(9y-6)=2/1#
We know if
Basically we are flipping and that would help us
#(9y-6)/4=1/2#
Let us multiply
#cancel(4)xx(9y-6)/cancel(4)=4xx1/2#
#9y-6 = 2#
To solve for
Let us start with
#9y-cancel(6)+cancel(6) = 2+6#
#9y=8#
#(cancel(9)y)/cancel(9) =8/9#
#y=8/9#
Let us check if our solution is correct by plugging
#4/(9y-6) = 2#
#4/(9(8/9)-6)=2#
#4/(8-6)=2#
#4/2=2#
#2=2 quad# this is a true statement so the solution is valid.
