8x - 3x - 2x
8x - 5x
3x
Solución :
3x
-------------------------------------------
(x + 4x) - (5x - 3x)
x + 4x - 5x + 3x
x + 4x + 3x - 5x
8x - 5x
3x
Solución :
3x
----------------------------------------------
5x - (2x + 1)
5x - 2x - 1
3x - 1
Solución :
3x - 1
------------------------------------------
2x - (4 - x)
2x - 4 + x
2x + x - 4
3x - 4
Solución :
3x - 4
--------------------------------------
(6x - 4) - (2x - 1)
6x - 4 - 2x + 1
6x - 2x - 4 + 1
4x - 3
Solución :
4x - 3
(x + 4x) - (5x - 3x ) = x +4x -5x +3x = 8x -5x = 3x
5x - (2x + 1) = 5x -2x -1 = 3x - 1
2x - ( 4 - x) = 2x -4 +x = 3x -4
(6x - 4) - (2x - 1) = 6x -4 -2x +1 = 4x -3
