Question

calculen el valor de x en cada una de las siguientes proporciones. (x+1)/2x = 3/4
x/1/2 =5/ 3/4
0.1/0.2 = x/0.3
(x+1)/2x = 3/4
(x+3)/5 = x-2/3
(2x-1/3)/2=1/4x-2/3​

Answer 1

(x+1)/2x =3/4

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

4x+4=6x

x= 2

x/1/2 = 5/3/4

x(3/4)= 1/2 (5/3)

3/4x=5/6

x= 10/9

0.1/0.2=x/0.3

0.2x= 0.3(0.1)

2/10x= 3/10(1/10)

2/10x=3/100

x= 3/20 = 0.15

(x+1)/2x = 3/4

4(x+1)=2x(4)

4x+4= 8x

x=1
