Answer 2

Respuesta:

1) x = -6

2) x = 8

3) x = -29/3

4) x = 10

5) x = 1/5

6) x = -1/3

Explicación:

1) 4x = 2x - 12

4x -2x = -12

2x = -12

x = -12/2

x = -6

2) 8x -24 = 5x

8x -5x = 24

3x = 24

x = 24/3

x = 8

3) 7x +12 = 4x -17

7x - 4x = -17 -12

3x = -29

x = -29/3

4) 3x -25 = x -5

3x - x = -5 +25

2x = 20

x = 20/2

x = 10

5) 5x + 13 = 10x + 12

5x - 10x = 12-13

-5x = -1 //-1

5x = 1

x = 1/5

6) 12x -10 = -11 +9x

12x -9x = -11 + 10

3x = -1

x = -1/3
