4 - 2x > -18. After you solve, graph your solution on a number line.

Question

Please help. This is on my review packet and I don't quite understand it.

Answer 1

   4 - 2x > -18

 

  -4             -4

 

     -2 x >  -22

 

Divide both sides by -2, reverse the inequality sign whenever

dividing or multiplying both sides by a negative number

 

         x < 11

 

On a number line, put an open circle around 11 and darken the 

number line going to the left of 11, everything less than 11 has 

been graphed
