Answer:

Explanation:

a)-2x-10<-14

-2x <-14+10

-2x< -4

  • Then divide both sides by -2.(REMEMBER:When you divide or multiply by a minus number the sign will be changed)

x>2

The number line is on the attachment.(remember: when you draw the number line you should not colour the circle)

b)x+4/3 < or = to -1

x+4/3 * 3 < or = to -1*3

x+4-4 < or = to -3-4

x < or = to -7

The number line is on the attachment.(remember: when you draw the number line you should colour the circle cause in here x is less than or equal to -7)

Hope this helps you
