y = gallons of a 50% solution
x = gallons of a 20% solution
equation 1
10 gallons are produced between the two solutions, which means you need to start with a total of 10 gallons.
equation 2
.5y + .2x = .38(10)


My last few sentences didn't appear on my answer......

equation 2

.5y + .2x = .38(10)

This equation is finding the correct ratio of the two solutions which must be used.
