Respuesta:
5(x-1) + 16(2x+3) = 3(2x-7) – x
5x-5 + 32x+48 = 6x-21 - x
37x + 43 = 5x - 21
37x - 5x = -43 - 21
32x = -64
x = -64/32
x = -2
2(3x+3) – 4(5x-3) = x(x-3) – x(x+5)
6x + 6 - 20x + 12 = - 3x -
- 5x
- 14x + 18 = - 8x
- 14x + 8x = -18
- 6x = -18
x = -18 / -6
x = 3
184 – 7(2x+5) = 301 + 6(x-1) – 6
184 - 14x - 35 = 301 + 6x - 6 -6
- 14x - 149 = 289 + 6x
- 14x - 6x = 289 + 149
- 20x = 140
x = 140 / -20
x = - 7
7(18-x) – 6(3-5x) = 2(7x+9) – 3(2x+5) – 12
126 - 7x - 18 + 30x = 14x + 18 - 6x - 15 -12
23x + 108 = 8x - 9
23x -8x = -108 -9
15x = - 117
x = -117 / 15
x = - 7.8
3(x-3) + 5(x+7) – x(x+1) – 2(x+7) + 4 = 0
3x - 9 + 5x + 35 - - x - 2x - 14 + 4 = 0
- + 5x + 16 = 0
- + 5x = - 16
- + x = -16 / 5
- + x = - 3.2
x + x =
2x = 1.78
x = 1.78 / 2
x = .89
-3(2x+7) + (-5x+6) – 8(1-2x) – (x-3) = 0
- 6x - 21 - 5x + 6 - 8 + 16x - x + 3 = 0
4x - 20 = 0
4x = 20
x = 20 / 4
x = 5
