Empecemos a resolver cada uno de los problemas :3
1) (x + 1)/6 = x/4 ===> MCM = 24 ===> (×24)
24 (x + 1)/6 = 24 (x/4) ===> Simplificas
4 (x + 1) = 6 (x)
4x + 4 = 6x
4 = 6x - 4x
4 = 2x ===> x = 4/2 ===> x = 2
2) (7x - 12)/6 = (x - 1)/3 ===> MCM = 6 ===> (×6)
6 (7x - 12)/6 = 6 (x - 1)/3 ===> Simplificas
1 (7x - 12) = 2 (x - 1)
7x - 12 = 2x - 2
7x - 2x = -2 + 12
5x = 10 ===> x = 10/5 ===> x = 2
3) (11x - 21)/1 = (3x - 2)/4 ===> MCM = 4 ===> (×4)
4 (11x - 21) = 4 (3x - 2)/4 ===> Simplificas
44x - 84 = 3x - 2
44x - 3x = -2 + 84
41x = 82 ===> x = 82/41 ===> x = 2
4) (6x - 6)/6 = (3x + 3)/5 ===> MCM = 30 ===> (×30)
30 (6x - 6)/6 = 30 (3x + 3)/5 ===> Simplificas
5 (6x - 6) = 6 (3x + 3)
30x - 30 = 18x + 18
30x - 18x = 18 + 30
12x = 48 ===> x = 48/12 ===> x = 4
5) (3x + 2)/8 = (19 - 7x)/5 ===> MCM = 40 ===> (×40)
40 (3x + 2)/8 = 40 (19 - 7x)/5 ===> Simplificas
5 (3x + 2) = 8 (19 - 7x)
15x + 10 = 152 - 56x
15x + 56x = 152 - 10
71x = 142 ===> x = 142/71 ===> x = 2
P.D. Las claves, en resumen son:
1) x = 2
2) x = 2
3) x = 2
4) x = 4
5) x = 2
Si tienes alguna duda, solo me avisas :3
Besitos y abrazos, y si quieres dame la coronita UvU
