• p = - 5

• p = 5

• p = 30

• p = - 6

Solve.
 $-19>-4x-3$  

•  $x<4$  

•  $x>-4$  

•  $x>4$  

•  $x<-4$  

Solve.
 $-\frac{3}{5}x+1>10$  

• x > -15

• x < -15

• x ≥ -3

• x ≤ -3

Find the error in the problem below
19 - 2k = 3k - 1
     +3k   +3k
19 + 1k = -1
-19           -19
k = -20

• They should have divided by 1 for the last step
• They should add 19 instead of subtracting 19
• I can not find an error
• Instead of adding 3k they should subtract 3k

Find the error.

• Adding 5x to each side instead of 5

• Subtracting 7 from both sides

• Dividing -4 by 2 equals 2

• Dividing both sides by 2
