0.10x+0.20y=0.17x+y

The equation gives a volume x , in gallons, of a 10% solution that could be mixed with a volume y , in gallons, of a 20% solution to produce a 17% solution. According to this equation, what volume, in gallons, of the 20% solution could be mixed with 90.0 gallons of the 10% solution to produce a 17% solution? (Assume that the volume of the mixture is the sum of the volumes of the two solutions before they were mixed.)

Use the exact value the question expects unless it says to round.
