Work Step by Step
4d+5≥13⟶ subtract 5 from each side
4d+5−5≥13−5⟶ subtract
4d≥8⟶ divide each side by 4
4d÷4≥8÷4⟶ divide
d≥2
or
7d−2<12⟶ add 2 to each side
7d−2+2<12+2⟶ add
7d<14⟶ divide each side by 7
7d÷7<14÷7⟶ divide
d<2
Since d is either less than, equal to, or greaater than 2, the solution set for d is all real numbers.
