por favor es urgente :|

Answer 1

4x - (2x - 1) + 5x - (4x - 2)

4x - 2x + 1 + 5x - 4x + 2

2x + 1 + x + 2

2x + x + 1 + 2

3x + 3

3x + (2x +3)  

3x + 2x + 3

5x + 3

(7x - 4) + (1 - 6x)  

7x - 4 + 1 - 6x

7x - 6x - 4 + 1

x - 3

2x - (x - 3) - (2x - 1)

2x - x + 3 -2x + 1

x + 3 - 2x +1

x - 2x + 3 + 1

-x +4

(x - 2) + (2x - 3) - (5x - 7)

x - 2 + 2x - 3 - 5x + 7

x + 2x - 5x - 2 -3 + 7

3x - 5x -5 + 7

-2x + 2

x - (x - 2)

x - x + 2

+2

(5x - 1) - (2x + 1)

5x - 1 - 2x - 1

5x - 2x - 1 - 1

3x - 2

(1 - 3x) - (1 - 5x)

1 - 3x - 1 + 5x

1 - 1 - 3x +5x

2x
