Question

¿Alguien sabe las comprobaciones de las siguientes ecuaciones? a) 8x+10=14 b) 3x+1=58 c) 2x´1/3=1

Answer 1

Resolver.

8x + 10 = 14
8x = 14 - 10
8x = 4
x = 4/8    Simplificas sacas 4ta
x = (4/4)/(8/4)
x = 1/2

Comprobacion.
8x + 10 = 14
8(1/2) + 10 = 14
4 + 10 = 14
  14    =  14
---------------------------------------------------------------------------------


3x + 1 = 58
3x = 58 - 1
3x = 57
x = 57/3
x = 19

Comprobacion

3x + 1 = 58
3(19) + 1 = 58
57 + 1 = 58
   58    =  58

-------------------------------------------------------------------------------------

2x + 1/3 = 1
2x = 1 - 1/3
2x = (3 - 1)/3
2x = 2/3
x = 2/(3 * 2)    Simplificas el 2
x = 1/3

Comprobacion.
2x + 1/3 = 1
2(1/3) + 1/3 = 1
2/3 + 1/3 = 1
(2 + 1)/3  = 1
3/3  = 1
  1  =  1

Answer 2

a) 8x+10=14
8x=14-10
8x=4
x=4/8
x=1/2

b) 3x+1=58
3x=58-1
x=57/3
x=19   

c) 2x+1/3=1
2x=1-1/3
2x=2/3
x=2/3/2
x=1/3
