Explicación paso a paso:

a) x = -2

8X-5X+10=12-8

3x = 4 - 10

x = -6/3

x = -2

b) x = 5

15-20+13X-8X=18+2

-5 + 5x = 20

5x = 20 + 5

x = 25/5

x = 5

c) x = 5

-9-11+6X-4X=5X-4X=5X-4X-15

-20 + 2x = x

-20 = x - 2x

-20 = -x

x = 20

20 = 5x - 4x - 15

20 = x + 15

20 - 15 = x

5 = x

d) = x = 17/8

5X-10+3×-5=4-6

5x + 3x - 5 = 12

8x = 17

x = 17/8

e) x = 5/6

7-X12-8=5X-4

-x12 - 8 = 5x - 3

-x = 5x + 5

-x - 5x = 5

-6x = 5

x = 5/6
