Question

4 (2X-8)-5x = S(1-3x) - 6 (2-x) -(4+ 3x)​

Answer 1

Resposta:

2x + 5 - 5x = - 1

- 3x = - 1 - 5

- 3x = - 6 (- 1)

  3x = 6

   x = 6/3

   x = 2

***********************

5 + 6x = 5x + 2

6x - 5x = 2 - 5

x = - 3

***************************

x + 2x - 1 - 3 = x

3x - 4 = x

3x - x = 4

2x = 4

x = 4/2

x = 2

***************************************

2x + 3x + 4 = 48 - 8x

5x + 4 = 48 - 8x

5x + 8x = 48 - 4

13x = 44

x = 44/13

****************************

10 - 9x + 2x = 2 - 3x

10 - 7x = 2 - 3x

10 - 2 = - 3x + 7x

8 = 4x

4x = 8

x = 8/4

x = 2

******************************

2 - 3x = - 2x + 12 - 3x

2 - 3x = - 2x - 3x + 12

2 = - 2x + 12

2x = 12 - 2

2x = 10

x = 10/2

x = 5

*************************

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

7x - 35 = 3x + 3

7x - 3x = 3 + 35

4x = 38

x = 38  (:2)

     -----  

      4   (:2)

x = 19/2

*****************************

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

3x - 6 = - 4x + 12

3x + 4x = 12 + 6

7x = 18

x = 18/7

***************************

2.(x + 1) - (x - 1) = 0

2x + 2 - x + 1 = 0

x + 3 = 0

x = - 3
