Respuesta:

a.5x = 8x - 15

5x - 8x = -15

3x = -15

x = -15/3

x = -5

b. 4x + 1 = 2

4x = 2 - 1

4x = 1

x = 1/4

c. 5x + 6 = 10x + 5

5x - 10x = 5 - 6

5x. = 1

x = 1/5

d. 8x - 4 + 3x = 7x + x + 14

8x +3x - 7x - x = 14 + 4

11 x - 7x - x = 18

- 4x - x = 18

- 5x = 18

x = 18/-5

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

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

27x - 18x + 60x + 657x = 242

9x + 60x + 657x = 242

726x = 242

x = 242/726 (simplificamos)

X = 121/363
