De coeficientes enteros con uso de parentesis : 2. 15x – 10 = 6x – (x + 2) + ( - x + 3) 4. 30x – ( - x + 6) + ( - 5x + 4) = - (5x + 6) + ( - 8 + 3x) 6. 3x + [ - 5x – (x + 3)] = 8x + ( - 5x – 9) 8. X – [5 + 3x – {5x – (6 + x)}] = - 3 10. 71 + [ - 5x + ( - 2x + 3) = 25 – [ - (3x + 4) – (4x + 3)] Por favor rapido.
En resumen
2. 15x – 10 = 6x – (x + 2) + ( - x + 3) 15x - 10 = 6x - x - 2 - x + 3 15x - 10 = 4x + 1 15x - 4x = 1 + 10 11x = 11 x = 11 / 11 x = 1 4.
2. 15x – 10 = 6x – (x + 2) + ( - x + 3)
15x - 10 = 6x - x - 2 - x + 3
15x - 10 = 4x + 1
15x - 4x = 1 + 10 11x = 11 x = 11 / 11 x = 1
4.
30x – ( - x + 6) + ( - 5x + 4) = - (5x + 6) + ( - 8 + 3x) 30x + x - 6 - 5x + 4 = - 5x - 6 - 8 + 3x 26x - 2 = - 2x - 14 26x + 2x = - 14 + 2 28x = - 12 x = - 12 / 28 x = - 3 / 7
6.
3x + [ - 5x – (x + 3)] = 8x + ( - 5x – 9)
3x + [ - 5x - x - 3 ] = 8x - 5x - 9
3x + [ - 6x - 3 ] = 3x - 9
3x - 6x - 3 = 3x - 9 - 3x - 3 = 3x - 9 - 3 + 9 = 3x + 3x 6 = 6x 6 / 6 = x 1 = x
8.
X – [5 + 3x – {5x – (6 + x)}] = - 3
x - [ 5 + 3x - {5x - 6 - x}] = - 3
x - [ 5 + 3x - {4x - 6}] = - 3
x - [ 5 + 3x - 4x + 6 ] = - 3
x - 5 - 3x + 4x - 6 = - 3 2x = - 3 + 5 + 6 2x = 8 x = 8 / 2 x = 4
10.
71 + [ - 5x + ( - 2x + 3)] = 25 – [ - (3x + 4) – (4x + 3)]
71 + [ - 5x - 2x + 3] = 25 - [ - 3x - 4 - 4x - 3]
71 + [ - 7x + 3 ] = 25 - [ - 7x - 7 ]
71 - 7x + 3 = 25 + 7x + 7 74 - 7x = 32 + 7x 74 - 32 = 7x + 7x 42 = 14x x = 14 / 42 = 2 / 6 x = 1 / 3 * Espero haberte ayudado, saludos.
Como ejemplo : (5x + 7x) - 4 + 7 = 5.
Primero se resuelve las operaciones dentro del paréntesis, en orden potencias, radicacion, multiplicación división y despues sumas y restas. Luego cuando se va el paréntesis resolves lo del corchete.
Jjmmm x3 + 4x + x - 6 y x - 7x + 6 nose xd.
