# Math Help - Algebraic Fractions

1. ## 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

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