Question

Resuelve las siguientes ecuaciones A x+2/6=1/2 B 5/3=3/7+y C 2/8+1/4=1/2-z D m-1/7=3/5 E 3/4+1/3=n-2/9 F -1/7+3/5-r=2/9 G 2/5-t-8/3=7 H 12/7x+3=-8 Ayuda es para mañana y la profe no explico el tema!!!

Answer 1

Ecuacion A:

x+2/6=1/2

x=1/2-2/6

x=3/6-2/6

x= 1/6

ECUACION B

5/3 = 3/7+y

-y= 3/7-5/3

-y= 9/21-35/21

-y= -26/21

y= 26/21

ECUACION C: 2/8+1/4=1/2-z

z= 1/2-2/8-1/4

z= 2/4-1/4-1/4

z= 2/4-2/4

z= 0

ECUACION D: m-1/7=3/5

m = 3/5+1/7

m= 21/35+5/35

m= 26/35

ECUACION E: 3/4+1/3=n-2/9

n= -2/9-3/4-1/3

n= -8/36-27/36-12/36

n= -47/36

ECUACION F: -1/7+3/5-r=2/9

-r= 2/9+1/7-3/5

-r= 70/315+45/315-189/315

-r= -74/315

ECUACION G 2/5-t-8/3=7

-t=7-2/5+8/3

-t= 7-6/15+24/15

-t= 7+18/15

-t= 7 3/15

-t= 7 1/5

t= -7 1/5

ECUACION H 12/7x+3=-8

12/7x=-8+3

12/7x = 5 

x= 5 entre 12/7

x= -35/12

Denada! ;)

Answer 2

Resolviendo las siguientes ecuaciones:

A) x + 2/6 = 1/2

x + 1/3 = 1/2

x = 1/2 - 1/3

x = -1/6

B) 5/3 = 3/7 + y

5/3 - 3/7 = y

y = 26/21

C) 2/8 + 1/4 = 1/2 - z

1/4 + 1/4 = 1/2 - z

2/4 = 1/2 - z

1/2 = 1/2 - z

z = 1/2 - 1/2

z = 0

D) m - 1/7 = 3/5

m = 3/5 + 1/7

m = 26/35

E) 3/4 + 1/3 = n - 2/9

3/4 + 1/3 + 2/9 = n

n = 47/36

F) -1/7 + 3/5 - r = 2/9

r = -1/7 + 3/5 + 2/9

r = 214/315

G) 2/5 - t - 8/3 = 7

2/5 - 8/3 - 7 = t

t = -139/15

H) 12/7x + 3 = -8

12/7x = -8 -3

12/7x = -11

x = -11 * (7/12)

x = -77/12
