- 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 !.
