5)Ten less than 6 times a number is greater than or equal to 2 more than twice the number.

Step-by-step explanation:

6x - 10 ≥ 2x + 2                  Subtract 2x from both sides

6x-2x - 10 ≥ 2x - 2x +2       Combine

4x - 10 ≥ 2                           Add 10 to both sides

4x - 10+ 10  ≥ 2 + 10            Combine

4x ≥ 12                                Divide by 4

4x/4   ≥   12/4                      Combine

x ≥ 3
