Question

Efetua e reduza o termo semelhante :


A) (-3/2 - y/3) + (x/5 - y/4) + (2x+y)

Answer 1

$(-\frac{3}{2} -\frac{y}{3} )\\ \\ mmc=6\\ \\ \frac{-9-2y}{6} \\ \\ (\frac{x}{5} -\frac{y}{4})\\ \\ mmc=20\\ \\ \frac{4x-5y}{20} \\ \\ -\frac{9-2y}{6} +\frac{4x-5y}{20} +\frac{2x+y}{1} =\\ \\ mmc=60\\ \\ \frac{-90-20y+120x-150y+120x+60y}{60} =\\ \\ \frac{240x-110y-90}{60}$
