Question 28296
1. 14 - 2x < 5
Subtract 14 from both sides
-2x < -9
Divide by -2. When dividing by a negative number, you have to change the sign of the inequality
{{{x > 9/2}}}


2. 3 - 2x < 9
-2x < 6
x > -3


3. -6 < 7x + 2 < 5
-8 < 7x < 3
{{{-8/7 < x < 3/7}}}


4.-6 < -2x < 8
3 > x > -4
-4 < x < 3
