“For Positive Numbers (p - q)/(p + q)”: Is it correct to say that because the equation has 2 variables, I can't solve the problem?

    Hi,

    Isnt p=5q in the below equation?

    (p-q) / (p+q) = 2/3

    3 (p-q) = 2 (p+q)

    3p - 3q = 2p + 2q

    3p-2p = 2q+3q

    p = 5q

     

    But as per the above given solution it is p=q. Please help me on this.
