Question

7x -3 = 25
5-9x=27
8-3x= -16
6x-4=4
7-4x=51
ayuda cuál es el valor de la x ​

Answer 1

Respuesta:

1) 7x-3 = 25

7x = 25+3

7x = 28

x = 28/7

x = 4

2) 5-9x = 27

-9x+5 = 27

-9x = 27-5

-9x = 22

x = -22/-9

3) 8-3x = -16

-3x+8 = -16

-3x = -16-8

-3x = -24

x = -24/-3

x = 8

4) 6x-4 = 4

6x = 4+4

6x = 8

x = 8/6

x = 4/6          (simplificamos)

                 

5) 7-4x = 51

-4x+7 = 51

-4x = 51-7

-4x = 44

x = 44/-4

x = -11
