    Simplifying an equation.

    Hello. I have an equation, and i need to solve it in order to find what y is equal to. Here it is:

    y = [-a[(fb - ec)/(bd - ea)] + c]/b

    If you can help, can you please give step by step instructions?

    It always helps to see it how it would be written on paper:

    \displaystyle \begin{align*} y = \frac{\frac{-a(fb-ec)}{bd-ea} + c}{b} \end{align*}

    Here you have fractions inside fractions. To start, it would help if the first numerator (which contains a fraction and a whole number) was written with a common denominator.
