Preciso de todas as questões e para hj!Por favor o mais rápido possível!!!!!

Answer 1

Olá!!!


Resolução!!!



A) 4x - 6 = 22

4x = 22 + 6
4x = 28
x = 28/4
x = 7


===============================

B) 9 - x = 2x

2x + x = 9
3x = 9
x = 9/3
x = 3


===============================

C) 8 + 4x = 6x - 4

4x - 6x = -4 - 8
-2x = -12
x = -12/-2
x = 6

===============================

D) 3x + 1 = x + 9

3x - x = 9 - 1
2x = 8
x = 8/2
x = 4

===============================

E) 4x - 11 = 7 - 2x

4x + 2x = 7 + 11
6x = 18
x = 18/6
x = 3

===============================

F) 13x + 1 - 10x = 5 + x

3x - x = 5 - 1
2x = 4
x = 4/2
x = 2




★Espero ter ajudado!! tmj.

Answer 2

A ) 4x - 6 = 22

4x = 22 + 6

x = 28/4

x = 7




B ) 9 - x = 2x

- x. - 2x = - 9

- 3x = - 9 ( - 1 )

3x = 9

x = 9/3

x = 3



C ) 8 + 4x = 6x - 4

4x - 6x = - 4 - 8

- 2x = - 12 ( - 1 )

2x = 12

x = 12/2

x = 6



D ) 3x + 1 = x + 9

3x - x = 9 - 1

2x = 8

x = 8/2

x = 4




E ) 4x - 11 = 7 - 2x

4x + 2x = 7 + 11

6x = 18

x = 18/6

x = 3




F ) 13x + 1 - 10x = 5 + x

13x - 10x - x = 5 - 1

2x = 4

x = 4/2

x = 2
