Question

Me ayudarían a despejar x?

8x-15x-30-51x=53x+31x-172

14-12x+39x-18x=256-60x-657x

16+7x-5+x=11x-3-x

11x+5x-1=65x-36

Answer 1

8x - 15x - 30 - 51x = 53x + 31x - 172

8x - 15x - 51x - 30 = 53x + 31x - 172

8x - 66x - 30= 84x - 172

- 58x - 30 = 84x - 172

- 58x - 84x = - 172 + 30

- 142x = - 142

x = -142/-142

x = 1

Solución : 

x = 1
-----------------------------------------------------------


14 - 12x + 39x - 18x = 256 - 60x - 657x

- 12x - 18x + 39x + 14 = 256 - 60x - 657x

- 30x + 39x + 14 = 256 - 717x

9x + 14 = 256 - 717x

9x + 717x = 256 - 14

726x = 242

x = 242/726

x = 1/3

Solución : 

x = 1/3
-----------------------------------------------

16 + 7x - 5 + x = 11x - 3 - x

7x + x + 16 - 5 = 11x - x - 3

8x + 11 = 10x - 3

8x - 10x = - 3 - 11

- 2x  =- 14

x = -14/-2

x = 7

Solución : 

x = 7
-----------------------------------------------

11x + 5x - 1 = 65x - 36

16x - 1 = 65x - 36

16x - 65x = - 36 + 1

- 49x = - 35

x = -35/-49

x = 5/7

Solución : 

x = 5/7
