URGEEEENTEE!!! ME AJUDEM A RESOLVER!!!?? POR FAVORR!!!!!!!!!

1)CALCULE O VALOR DE X EM CADA PROPORÇÃO:

a) 2x\ x+1 - 9\6

b) x+2\5 = 2x\5

Answer 1

$\frac{2x}{x+1}= \frac{9}{6}$

$6(2x) = 9(x+1)$

$12x=9x+9$

$12x-9x=9-->3x=9-->x=3$

_____________________________________________
$\frac{x+2}{5}= \frac{2x}{5}$

$5(x+2)=5(2x)$

$5x+10=10x$

$10=10x-5x -->10=5x-->x=2$
