Respuesta:
a) 3 + 4(x - 2) = - 3 - 5(x - 5)
3 + 4x - 8 = - 3 - 5x + 25
4x - 5 = 22 - 5x
4x + 5x = 22 + 5
9x = 27
x = 27 / 9
x = 3
b) 3x + 5(x + 2) = 4(x + 3) + 6
3x + 5x + 10 = 4x + 12 + 6
8x + 10 = 4x + 18
8x - 4x = 18 - 10
4x = 8
x = 8 / 4
x = 2
c) 5 - 4(3x + 1) = 1 + 4(2x + 20)
5 - 12x - 4 = 1 + 8x + 40
1 - 12x = 41 + 8x
1 - 41 = 8x + 12x
- 40 = 20x
- 40 / 20 = x
- 2
d) 9(x - 3) = 2(x - 5) - 3
9x - 27 = 2x - 10 - 3
9x - 27 = 2x - 13
9x - 2x = - 13 + 27
7x = 14
x = 14 / 7
x = 2
e) 5(2x - 3) - 6 = 4x + 3
10x - 15 - 6 = 4x + 3
10x - 21 = 4x + 3
10x - 4x = 3 + 21
6x = 24
x = 24 / 6
x = 4
f) 3(x - 2) + x = 5(x - 3) + 9
3x - 6 + x = 5x - 15 + 9
4x - 6 = 5x - 6
- 6 + 6 = 5x - 4x
0 = x
