Mixture Problem Help

Im having trouble understanding mixture problems. (and all the other ones like distance,work rate)

So my question is...

Victor is making orange juice. He has one pitcher that contains 2 quarts of 50% concentrate, and another pitcher that contains 4 quarts of 20% concentrate. If he combines the two pitchers, how many quarts of water must he add so that he ends up with a mixture containing 25%?

A) 0.5
B)1
C) 1.2
D) 2.4

let x = quarts of added water

2(.5) + 4(.2) + x(0) = (6+x)(.25)

Thanks! :D

I wasn't putting x for water. :)
