    Question Steps to Transpose an Equation

    Hello,

    Iím brand to this site and Iím hoping that someone can show me the individual steps that allows the following equation:

    t = P*R/S*E-0.6*P

    Transpose to make P the subject per the following equation:

    P = S*E*t/R+0.6t

    Many Thanks,

    Rich.

    I've managed to figure this out by looking at similar posts (Sorry... I did say I was new!)

    Anyway, here are the steps to transpose t = P*R/S*E-0.6*P making P the subject:

    If that the case (denominator as you show) then
    your equation requires brackets: t = P*R / (S*E-0.6*P) ; understand?
    Crossmultiply:
    PR = tSE - .6tP
    Add .6tP to each side:
    PR + .6tP = tSE
    Factor left side:
    P(R + .6t) = tSE
    Divide each side by R + .6t:
    P = tSE / (R + .6t) : notice brackets to CLARIFY denominator!
    That's it.

    Usually with these, you'd be expected to change .6 to 3/5, thus 3t / 5; so:
    P = tSE / (R + 3t/5)
    P = tSE / [(5R + 3t) / 5]
    P = 5tSE / (5R + 3t)
    Capish?

    Got it,

    Thanks for (Clarifying) that for me!
