6-2(2x-1/2)=4x-2(3/4-3x)

5x-(2x+(3-x))=11

1-(x-(x-(x-1)))=0

Answer 1

6 - 2(2x - 1/2) = 4x - 2(3/4 - 3x)

6 - 4x + 1 = 4x - 3/2 + 6x

- 4x - 4x - 6x = - 6 - 1 - 3/2

- 14x = - 7 - 1 1/2

- 14x = - 8 1/2

- 14x = - 17/2 / · (- 1/14)

x = 17/28

 

5x - (2x + (3 - x)) = 11

5x - (2x + 3 - x) = 11

5x - 2x - 3 + x = 11

4x = 14

x = 14/4

 

1 - (x - (x - (x - 1)))=0

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

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

1 - x + x - x + 1 = 0

- x = - 2

x = 2
