Hi Jerry;

[(2 hours)/(1 day)](14 days)=(18+x)hours

Let's note that the unit of day is in the numerator and denominator. It cancels...

[(2 hours)/(1 day)](14
days)=(18 hours)+(x hours)

(2 hours)(14)=(18+x)hours

Let's note that the unit of hours is in the numerators of both sides of the equation. It cancels...

(2 hours)(14)=(18+x)hours

(2)(14)=18+x

28=18+x

10=x

HE WILL HAVE TO STUDY 10 HOURS.
