Question

ECUACIONES LINEALES CON COEFICIENTES FRACCIONARIOS:


A) X/5 + 9 = 27/2


B) 17/4 - X/6 = 25/12


C) X/4 - X/3 = 1/3


D) 3/4 + Z/5 = 61/60


E) 4X/3 + 5/2 = 1/4 - X

Answer 1

A) X/5 + 9 = 27/2

2x/5+18=27

2x/5=9

2x=45

x=45/2

B) 17/4 - X/6 = 25/12

204/4 -12x/6=25

51-12x/6=25

26=12x/6

156=12x

13=x

C)X/4 - X/3 = 1/3

-x/12=13

-x=156

-156=x

D)3/4 + Z/5 = 61/60

3/4-61/60=z/5

45/60 - 61/60=z/5

-6/60=z/5

-30=60z

-1/2=z

E) 4X/3 + 5/2 = 1/4 - X

10/4 - 1/4 =4x/3  -X

9/4  =4X^2 /3

27 =16X^2

27/16 =x^2

$\sqrt[2]{27}$ /4 =X
