    How to solve this mathematic??


    Can anyone help me how to solve this? I wat to solve for X
    0.0032 = (x/100 * 0.0556) + (y/100 * 0.0153)

    Should I do it like this?
    0.0032 = (x/100 * 0.0556) + (100-x/100 * 0.0153)

    ... And how to solve it [?]

    Edit: I assumed you were using standard notation, i.e. your equation was:

    [tex].0032 = \frac{.0556x}{100} + \frac{.0153y}{100}[/tex]

    Subtract .0153y/100 from both sides. Multiply both sides by 100. Divide both sides by .0556.

    Notice how each layer of complexity is just kind of peeled away one at a time. Just break it down into little steps and you should find it's easier.

    Thanks you for replay

    At the end I got this:-

    0.0576 - 0.275 y = x

    What do to next to get the number of "X" ??

    I'm still at the same problem :\

    Could you give me the answer of "x" and how did you get it, please?

    You need more information (such as another equation) to be able to uniquely determine x. Of course, if you're interested in /a/ value of x, you could just set y = 1 (or something else) and evaluate the expression...
