Question

me ajudem como resolver eu esqueci

Answer 1

$\frac{x-1}{3} + \frac{4x+1}{6} = \frac{5}{10}$$= \frac{1}{2}$ ---> mmc (3,6,2) =6

$2(x-1)+(4x+1)=3$

$2x-2+4x+1=3-->6x=3+1-->6x=4$

$x= \frac{4}{6}-->x= \frac{2}{3}$
__________________________________________________
$\frac{1-2x}{3}- \frac{3-3x}{7}= \frac{x}{2}$
mmc(3,7,2)=42

$14(1-2x)-6(3-3x)=21x$

$14-28x-18+18x=21x --->-10x-21x=-4$

$-31x=-4 (-1)-->31x=4-->x=4/31$
___________________________________________
$\frac{1-2x}{3} - \frac{2-3x}{7}= \frac{x}{2}$

$14(1-2x)-6(2-3x)=21x$

$14-28x-12+18x=21x$

$-10x-21x=2->-31x=2->31x=-2->x= \frac{-2}{31}$
