Answer 1

Resposta:

$( \frac{x}{3} + \frac{xy}{2} - \frac{y}{5} ) - ( \frac{3y}{2} - \frac{2xy}{5} + \frac{x}{4} ) = \\ \frac{x}{3} + \frac{xy}{2} - \frac{y}{5} - \frac{3y}{2} + \frac{2xy}{5} - \frac{x}{4} = \\ \frac{x}{3} - \frac{x}{4} + \frac{xy}{2} + \frac{2xy}{5} - \frac{y}{5} - \frac{3y}{2} = \\ \frac{4x - 3x}{12} + \frac{5xy + 4xy}{10} - \frac{2y - 15y}{10} = \\ \frac{x}{12} + \frac{9xy}{10} - \frac{17y}{10}$
