Ayuda 6x + 6 = 4 + 84 9 + 9x = 17 + 5x 25 - 2x = 3x + 20 4x + 1 = 3x + 3 5x - 3 = 19x - 6 1 + 8x = 16x + 31 5x - 11 = 15x - 30 12x - 48 = - 15x - 30.
En resumen
1) 6x + 6 = 4 + 84 6x = 88 - 6 x = 82 / 6 x = 13.
1)
6x + 6 = 4 + 84
6x = 88 - 6
x = 82 / 6
x = 13.
6
__________
2)
9 + 9x = 17 + 5x
9x - 5x = 17 - 9
4x = 8
x = 8 / 4
x = 2
____________
3)
25 - 2x = 3x + 20
25 - 20 = 3x + 2x
5 = 5x
5 / 5 = x
1 = x
________________
4)
4x + 1 = 3x + 3
4x - 3x = 3 - 1
x = 2
________________
5)
5x - 3 = 19x - 6 - 3 + 6 = 19x - 5x
3 = 14x
3 / 14 = x
________________
6)
1 + 8x = 16x + 31
1 - 31 = 16x - 8x - 30 = 8x - 30 / 8 = x
⬆le sacas la mitad - 15 / 4 = x
_________________
7)
5x - 11 = 15x - 30 - 11 + 30 = 15x - 5x - 19 = 10x - 19 / 10 = x
__________________
8)
12x - 48 = - 15x - 30
12x + 15x = - 30 + 48
27x = 18
x = 18 / 27
⬆Les sacamos novena
x = 2 / 3

Adios.
La respuesta es - 10. 75 o - 43 / 4.
Sea la cantidad de paletas grandes "x" y la cantidad de paletas chicas "y" : Ecuacion (I) 5x + 3y = 570 . (I) Ecuacion (II) x + y = 150 x = 150 - y . (II) Sustituimos (II) en (I) 5x + 3y = 570 5(150 - y) + 3y = 570 750…
Resolver. [( + 6). ( + 7]⁵ = [ 6 * 7]⁵ = 42⁵ Respuesta. 42⁵.
