Question

x/6+x/12+x/7+5+x/2+4=

Answer 1

Resposta:

$\frac{x}{6}+ \frac{x}{12} +\frac{x}{7} +5+\frac{x}{2} +4=\\ \\ mmc~de~6,~12,~7,~2~|~2\\ ~~~~~~~~~~~~~3,~~6,~7,~1~|~2\\ ~~~~~~~~~~~~~3,~~3,~7,~1~|~3\\ ~~~~~~~~~~~~~~1,~1,~7,~1~|~7\\ ~~~~~~~~~~~~~~1,~1,~1,~1\\ \\ mmc=2^{2}.3.7=84\\ \\ \frac{14+7+12+420+42+336}{84} =\frac{831}{84} ~~simplificando~por~3= \frac{277}{28}$
