find all number such that 6 less than one third of a number is at least 35

Question

Hi help write the eqution

Answer 1

"6 less than one third of a number is at least 35"      means

            (1/3)z  - 6                           ≥   35

 

(1/3)x - 6 ≥ 35

    x - 18 ≥  105            [multiply both sides by +3 retains sense of inequality]

     x  ≥  123             [Note: this is an inequality]
