    1. The problem statement, all variables and given/known data

    Hi .

    I found this in my textbook. I want to know how they got to the answer. I really dont know how they got it.

    [tex]\frac{\frac{x}{2}}{0.40-\frac{x}{2}}[/tex]= 6.8 x 10-2
    x= 0.0272 - 0.068x
    x= 0.025

    2. Relevant equations

    3. The attempt at a solution
    i just dont know where to start or how to solve this.

    Multiply both sides by 0.4-x/2
