Resolver las siguientes ecuaciones 10x + 3 - 7x = 5 + 10 + 6×.
Resolver las siguientes ecuaciones 10x + 3 - 7x = 5 + 10 + 6×.
En resumen
10x + 3 - 7x = 5 + 10 + 6x 10x + 3 - 7x - 6x = 5 + 10 10x + 3 - 7x - 6x = 15 10x - 7x - 6x = 15 - 3 10x - 7x - 6x = 12 3x - 6x = 12 - 3x = 12 x = 12 : - 3 x = - 4 Comprobamos : 10x + 3 - 7x = 5 + 10 + 6x 10. - 4 + 3 - 7. - 4 = 5 + 10 + 6.
10x + 3 - 7x = 5 + 10 + 6x
10x + 3 - 7x - 6x = 5 + 10
10x + 3 - 7x - 6x = 15
10x - 7x - 6x = 15 - 3
10x - 7x - 6x = 12
3x - 6x = 12 - 3x = 12
x = 12 : - 3
x = - 4
Comprobamos :
10x + 3 - 7x = 5 + 10 + 6x
10.
- 4 + 3 - 7.
- 4 = 5 + 10 + 6.
- 4 - 40 + 3 - ( - 28) = 5 + 10 + - 24 - 37 - ( - 28) = 15 + - 24 - 37 + 28 = 15 + - 24 (Suprresión de paréntesis) - 9 = - 9.
10x - 7x - 6x = 5 + 10 - 3 - 3x = 12
x = 12 / - 3
x = - 4.
. Espero que te sirva, salu2!
7x / 10 = 28 7x = 280 x = 40 (16x + 40 - 120) / 8 = x + 2 16x - 80 = 8x + 16 8x = 96 x = 12 (2x + 2 + 14x) / 14 = x - 2 2x + 2 + 14x = 14x - 2 2x + 2 = - 2 2x = - 4 x = - 2 (16x + 24 - 25x + 10) / 40 = (31x + 27) / 6…
