3.5d+2=7-1.5d

Subtract 2 from both sides

3.5d=5-1.5d

Add 1.5d to the other side

5d=1.5d

d=3.33

We have given that,

Machine 1 can complete a task in x hours while an upgraded machine (machine 2) needs 9 fewer hours.

We have to determine the,

The plant manager knows the two machines will take at least 6 hours, as represented by the inequality

after you find the intervals.

you also need to consider that the plant manager knows the two machines will take at least 6 hours.

so (0, 3] is taken out of the picture leaving you with B.
