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.
