Tema
- 4x + 12 – 15
5 x + 17 = 2
- 6X+4 = - 2
8x + 6 = -2
5x = 4x+1
-3x+4 =-5
2x-1= -7​

Answer 1

- 4x + 12 = 15

- 4x = 15 - 12

- 4x = 3

x = 3 : (- 4) = - 0,75

_____________

5x + 17 = 2

5x = 2 - 17

5x = - 15

x = - 15 : 5 = - 3

_____________

- 6x + 4 = - 2

- 6x = - 2 - 4

- 6x = - 6

x = 6 : 6 = 1

_____________

8x + 6 = - 2

8x = - 2 - 6

8x = - 8

x = - 8 : 8 = - 1

_____________

5x = 4x + 1

5x - 4x = 1

x = 1

_____________

- 3x + 4 = - 5

- 3x = - 5 - 4

- 3x = - 9

x = 9 : 3 = 3

_____________

2x - 1 = - 7

2x = - 7 + 1

2x = - 6

x = - 6 : 2 = - 3
