    tricky fraction problem

    the sum of the numerator and the denominator of a certain fraction is 104. the value of the fraction reduces to 9/17. What is the fraction?

    so confusing


    thanks

    x+y = 104

    \frac{x}{y} = \frac{9}{17}

    two equations, two unknowns ... solve the system of equations for x and y
