Question

3(
$3( \frac{x - 1}{5} ) - 2x = 5( \frac{x - 3}{6} )$
​

Answer 1

Resposta:

Primeiro vamos realizar as multiplicalções

$3(\frac{x-1}{5})-2x=5(\frac{x-3}{6})\\\\\frac{3x-3}{5} -2x = \frac{5x-15}{6}$

agora vamos colocar tudo na mesma base

$\frac{3x-3-10x}{5} = \frac{5x-15}{6}$

só multiplicar em cruz e isolar o x:

$(-7x-3)(6)=(5x-15)(5)\\\\-42x-18=15x-75\\\\-57x=-75+18\\\\-57x=-57\\\\x= \frac{-57}{-57} \\\\x=1$
