Question

Halla la solución de las ecuaciones:
A) -5 (6-5X) = 5X - 10
B) 16+5X = X - 3 (4+X)
C) -3 (6 - 6X) -3 = X - 4
D) -6X = 3 (5X +8) -3

Answer 1

- 5 (6 - 5x) = 5x - 10

- 30 + 25x = 5x - 10

25x - 5x = - 10 + 30

20x = 20

x = 20/20

x = 1
---------------------------------------
16 + 5x = x - 3 (4 + x)

16 + 5x = x - 12 - 3x

5x - x + 3x = - 12 - 16

7x = - 28

x = -28/7

x = - 4 
------------------------------------------

- 3 (6 - 6x) - 3 = x - 4

- 18 + 18x - 3 = x - 4

18x - x = - 4 + 3 + 18

17x = 17

x = 17/17

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

- 6x = 3 (5x + 8) - 3

- 6x = 15x + 24 - 3

- 6x - 15x = 24 - 3

- 21x = 21

x = -21/21

x = - 1
