Solving+Single+Variable+Inequalities



EXAMPLES: x-4__<__9 1.)Add 4 to both sides

x-4+4__<__9+4 2.) Combine like terms

x__<__13

2(-x+3)>-3(2x+6) 1.) Distribute

-2x+6>-6x-18 2.) Add 6x to both sides

-2x+6**+6x**>-6x-18**+6x** 3.) Combine like terms

4x+6>-18 4.) Subtract 6 from both sides

4x+6**-6**>-18**-6** 5.) Combine like term

4x>-24 6.) Divide both sides by 4

x>-6

5<-3x-4__<__17 1.) Add 4 to all sides

5+4<-3x-4+4__<__17+4 2.) Combine like terms

9<-3x__<__21 3.) Divide all sides by -3. *Remember to reverse inequality signs

9/-3**>**-3x/-3**__>__**21/-3 4.) Simplify

-3>x__>__-7
