Resposta:

-1,5; 19/13; -9.

Explicação passo a passo:

2 . (4x - 3) = 4 . (x - 3)

8x - 6 = 4x - 12

8x - 4x = - 12 + 6

4x = - 6

x = - 6 : 4

x = - 1,5.

8 . (3 - x) = 5 . (x + 1)

24 - 8x = 5x + 5

- 8x - 5x= 5 - 24

- 13x = - 19  .(-1)

13x = 19

x = 19/13.

6 . (x - 5) = 4 . (3x + 6)

6x - 30 = 12x + 24

6x - 12x = 24 + 30

- 6x = 54  .(-1)

6x = - 54

x = - 9.

1) x = -3/2

2) x = 19/13

3) x = -9

1) 2(4x-3)=4(x-3)

8x-6 = 4x-12

8x-4x = -12+6

4x = -6

x = -6/4, simplificando -3/2

2) 8(3-x)=5(x+1)

24-8x = 5x+5

-8x-5x = 5-24

-13x = -19

x = 19/13

3) 6(x-5)=4(3x+6)

6x-30 = 12x+24

6x-12x = 24+30

-6x = 54

x = -54/6

x = -9
