you would just break each one into 2 separate equations and solve for x/r. Then write the answer in between the two inequality signs- so the answers for 9 and 11 would look like this, just fill in the blanks with the answer you got: 3≤____<5, 2>___>-2.
0≤x-2<3
1≤x-2 and x-2<3
-1>2r-5>-9
-1>2r-5 and 2r-5>-9
this one just solve each one for z.
2z-1≤5 or 3z-5>10
z≤3 or x>5
