Resolver: Solución:
m.c.m. 5, 3, 2, 3 = 30
5 = 5
3 = 3
2 = 2
6x - (10x - 20) + 15x = 130
6x - 10x + 20 + 15x = 130
11x = 110
x = 10 Valor igualdad: 4,333 = 13/3
Resolver:
x/4 - 3x/2 + x = 4x/8 - 3 Solución:
m. c. m 4,2,8 = 8
4= 22
2=2
8=23
2x - 12x + 8x = 4x - 24
24 = 6x
x = 4 Valor igualdad: -1
Resolver:
Solución:
3x - 9 + 2x = 120 - 3x + 57
8x = 186
x = 93/4 = 23,25 = 231/4
Resolver:
2x - x/2 + 1 = 5x -2
Solución:
4x - x + 2 = 10x - 4
6 = 7x
x = 6/7
Valor igualdad:
16/7
Resolver:
x + x/2 + x/3 = 11 Solución:
6x + 3x + 2x = 66
11x = 66
x = 6
Valor igualdad: 11
Resolver:
6 - 2x + 10 = 20 - 3x - 2 Solución:
x = 2
Valor igualdad: 12
