b) X+1/18 = 2/6

C) 4/2x = 6/X+2

D) X - 4/X+6 = 9/24

E) 3,5/X+8 = 2,1/3x

F) 5x/X+1= 1/2

URGENTE!!!

Answer 1

a) 32/24=20x
1,3.20= x
x= 26

b) x+1/18=2/6
x/18=0,3
x=0,3.18
x= 5,4

c) 4/2x=6/x+2
2x-2x=6.4
x= 24

d) x-4/x+6=9/4
-4x/6x=-0,6x
x= -0,6 

e) 3,5/8x=2,1/3x
8x.3x=2,1-3,5
24x= -1,4
x= -1,4/24= -0,05

f) 5x/x=0,5
x=0,5.5
x= 2,5
