    the total number of liters of water is not something you have to find, it is 1 liter what you have to find is the liters of lemon juice name a variable, and say that it represents the number of liters of lemon juice

    you don't need two variables, one will do

    especially since it says "Write an equation in ONE variable "

    ok, but we have to find the total of lemon juice and water, not just lemon juice, so i didnt knoe...

    if J is the amount of lemon juice and there is one liter of water, then the total amount is \[J+1\] which is why you don't need another variable

    then \(60\%\) of the total is lemon juice, the total is \(J+1\) so you can write an equation \[J=0.6\times (J+1)\] and solve that for \(J\)

    if you do it correctly you should get \(J=1.5\)

    Like @misty1212 said, "J=0.6×(J+1) and solve that for J" First step is J=0.6J+0.6 OK?

    no, group all terms with the variable J on to one side....

    J=0.6J+0.6 so which term includes the variable J

    And J on the left hand side! Move them all to one side but subtracting 0.6J
