10x/2 + 5x/3 - 4x/4 = 2
Sacamos el mcm de los denominadores = 12
60x + 20x - 12x
------------------------ = 2
12
60x + 20x - 12x = 12 (2)
80x - 12x = 24
68x = 24
x = 24/68
x = 6/17
Respuesta.
x = 6/17
5x+5x/3-1x= 2
5 5/3x - 1x= 2
20x/3-1x= 2
20x/3-3x/3= 2
17x/3= 2
17x=3(2)
17x= 6
x= 6/17
Comprobación
10/2x+5/3x-4/4x=2
5x+5/3x-x=2
5(6/17)+(5/3)(6/17)-6/17=2
30/17 + 30/51 - 6/17= 2
24/17+30/51= 2
72/51+30/51= 2
102/51=2
