Question

Alguém pode me ajudar? E uma pergunta simples... Eu acho.

Answer 1

Resposta:

$a)(+\frac{1}{2} x)+(-\frac{1}{3} x)\\\\\frac{1}{2} x-\frac{1}{3} x\\\\x(\frac{1}{2} -\frac{1}{3} )\\\\x\frac{1}{6} \\\\\frac{x \ . \ 1}{6} \\\\\frac{x}{6}$

$e)(+\frac{3}{3} x)-(-\frac{3}{2} x)\\\\\frac{3}{3} x+\frac{3}{2} x\\\\x(\frac{3}{3} +\frac{3}{2} )\\\\x(1+\frac{3}{2} )\\\\x\frac{5}{2} \\\\\frac{x \ . \ 5}{2} \\\\\frac{5x}{2}$
