Question

ejercicios con ecuaciones racionales de primer grado : A)11/6X-1/5=2 B)2/3+X=7/9 C ) 1/2X-2=1-1/4 D)5/6-32X=0 Y E) 2/3+X=7/9​

Answer 1

A)11/6X-1/5=2

(55x-6)/30=2

55x-6 = 60

55x=60+6

x = 66/55

x=6/5

B)2/3+X=7/9

(2+3x)/3 = 7/9

9(2+3x) = 7*3

18+27x = 21

27x = 21-18

x = 3/27

x = 1/9

C ) 1/2X-2=1-1/4

(x-4)/2 = (4-1)/4

4(x-4) = 2*3

4x-16 = 6

4x = 16+6

x = 22/4

x = 11/2

D)5/6-32X=0

(5-192x)/6=0

5=192x

x = 192/5

E) 2/3+X=7/9​

(2+3x)/3 = 7/9

9(2+3x) = 7*3

18+27x = 21

27x = 21-18

x = 3/27

x = 1/9
