    Algebraic Fractions

    I'm working from an algebra workbook and one of the questions has me stumped.

    Picture: First one is the correct answer, and the second one is the one I thought it would be.



    Why am I wrong?

    Because \frac{3-2x}{2}=\frac{3}{2}-\frac{2x}{2}.

    You must use this rule for algebraic substraction

    \displaystyle \frac{a-bc}{b}=\frac{a}{b}-\frac{bc}{b}=\frac{a}{b}-c
