Question

a + 14 < 13
i'd like to know if the answer to that problem is; a > -1

Answer 1

No.
Subtract 14 from both sides.
The inequality sign does not change direction.
a + 14 < 13
- 14 -14
----------------
a < -1
Solution is: a < -1

Answer 2

oh, thanks. Are you saying the signs never change? since it stayed <

Answer 3

they signs only change when you divide by a negative

Answer 4

thanks

Answer 5

The inequality sign changes when you multiply or divide both sides by a negative number.
The inequality sign does not change when you add or subtract any number to both sides or when you multiply or divide both numbers by a positive number.
