Answer 2

Respuesta:

$3-x+\frac{2}{5}=5\left(3x-2\right)\quad :\quad x=\frac{67}{80}\quad \left(\mathrm{Decimal}:\quad x=0.8375\right)$

$Pasos\\\\3-x+\frac{2}{5}=5\left(3x-2\right)$

$\mathrm{Convertir\:a\:fraccion}:\quad \:3=\frac{3\cdot \:5}{5}\\\\\frac{3\cdot \:5}{5}+\frac{2}{5}=5\left(3x-2\right)\\\\\mathrm{Ya\:que\:los\:denominadores\:son\:iguales,\:combinar\:las\:fracciones}:\quad \frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}\\\\\frac{3\cdot \:5+2}{5}=5\left(3x-2\right)\\\\3\cdot \:5+2=17\\\\-x+\frac{17}{5}=5\left(3x-2\right)\\\\\mathrm{Desarrollar\:}5\left(3x-2\right):\quad 15x-10\\\\-x+\frac{17}{5}=15x-10$

$\frac{-16x}{-16}=\frac{-\frac{67}{5}}{-16}\\\\\mathrm{Simplificar}\\\\x=\frac{67}{80}$

Alaaa, mi cerebro jaja :"3 .
