When solving inequalities, When do you flip the inequality?

• Never

• Always

• When there are negatives

• When you multiply or divide a negative on both sides

• When you subtract a negative on both sides

Solve the inequality:

4x > 12

• x > 3

• x < 3

• x > 8

• 

  $x\ge3$

 $-5x\ <\ -10$  

•  $x\ <\ -2$  

•  $x\ <2$  

•  $x\ >-2$  

•  $x\ >2$  

 $\frac{x}{2}+3\ >\ 9$  

• x < -12

• x > 12

• x < 15

• x > 15

True or False: Solving inequalities is like solving equations because inverse operations are done to isolate the variable.

• true

• false

If there are variables on the same side of the equation, what should your first step be?

• Add on both sides

• Subtract on both sides

• Combine like terms: Add the letters

• Eliminate one of the variables

 $Solve\ for\ 3x-2+2x=13$  

• x = 15

• x = 3

• x = 1

• x =  -15

Solve for x,

3(4x-2) = 6

• 12x

• x = 0

• x = 3

• x = 1
