Step 1      -          1      5        ⋅    n    ≤    21                or              -    n    ≤    105                or              n    ≥    -    105   or       -          1      5        ⋅    n    ≤    21                or              -    n    ≤    105                or              n    ≥    -    105   or       -          1      5        ⋅    n    ≤    21                or              -    n    ≤    105                or              n    ≥    -    105  Solution:       n    ≥    -    105   . In interval notation expressed as             [      -      105      ,      ∞      )
