Answer:
x< -
Step-by-step explanation:
x 8x_16>8x+64
Add similar elemants:x - 8x= -7x
-7x - 16 > 8x + 64
Add 16 to both sides
-7x- 16 + 16 > 8x + 64 + 16
Simplify
- 7x > 8x + 80
Subtract 8x from both sides
-7x - 8x > 8x + 80 - 8x
Simplify
-15x > 80
Multiply both sides by - 1 ( reverse the inequality)
(-15x) ( - 1) < 80 ( - 1 )
simplify
