1) 8-3x < 14

-3x/-3 < 6/-3

x=-2

2) 7x -3 > 4x +3

3x -3> 3

3x/3 >6/3

x>2

3) x-5<3 and 2x > -8

x<8 x>-4

4) x+ 7 <3 or 5x > 30

x<-4 x> 6

are they correct..

**Quidditch**, Thursday, July 15, 2010 at 10:28pm1. The solution is an inequality. Also when you multiply or divide by a negative number, the inequality is reversed.

from you step:

-3x/-3 < 6/-3

Since you are dividing both sides by a negative number the inequality is flipped:

x > -2

2. OK
