- 8 x  + 2 - 16 < 5 x + 7x 

Simplify: ( add / subtract numbers : 2 - 16 )

- 8 x + 2 - 16

- 8 x + 14

Simplify 5x + 7x  = 12 x

-8 x - 14 < 12 x

add 14 to both sides:

- 8 x - 14 + 14 < 12 x + 14

-8 x < 12 x + 14

Subtract 12 x from both sides:

- 8 x - 12 x < 12 x + 14 - 12 x

- 20 x < 14

Multiply both sides by -1 ( reverse the inequality )

(-1) (-20 x ) > ( -1 ) ( 14 )

20 x > - 14

Divide both sides by 20 :

20 x / 20 > -14 / 20

x > - 7 / 10

hope this helps !.
