Answer 1

Respuesta:

1.

3x + 101 +4x-33-51x=-53x+31x-172

(3x + 4x - 51x) + (101 - 33) = (-53x + 31x) - 172

-44x + 68 = -22x - 172

-22x = -240

x = -240/-22

x = 120/11

2.

3x - 14 - 12x +18x = 256 + 60x - 657x

(3x -12x + 18x) - 14 = 256 + (60x - 657x)

9x - 14 = 256 - 597x

x = 606/270

x = 45 / 101

3.

-8x+15x+30x-51x=53x-31x-100

-14x = 22x - 100

100=36x

x = 100/36

x = 25/9

4.

9x - (5x + 3) - {2 + 8x - (7x-5)} - 9x =0

9x - 5x - 3 - {2 + 8x -7x +5} - 9x = 0

4x - 3 - {7 + x} - 9x = 0

4x - 3 -7 - x - 9x = 0

-6x = 10

x = 10/ -6

x= - 5/3
