    Re: Drawing Linear Equation

    Hey xdamagedxkissesx.

    Just expand out both sides and try and solve for y: there is nothing mysterious about the question.

    Re: Drawing Linear Equation

    3/4(y 1/5) = 1/8(y + 2/5)
    3/4[(5y 1)/5] = 1/8[(5y + 2)/5]
    3/20[(5y 1)] = 1/40[(5y + 2)]
    3(5y 1)/20 = 1(5y + 2)/40 --------- LCM 40
    [6(5y 1) = 1(5y + 2)]/40
    30y 6 = 5y + 2
    25y = 8
    y = 8/25 ----- 1 value

    Re: Drawing Linear Equation

    simplify
    3/4y-3/20= -1/8y-2/40
    30y-6=-5y-2
    35y=4 y=4/35
