The ratio of rooms in a hotel that are occupied to unoccupied are in the
ratio 6:5. The next morning, people check out of 230 of the rooms. Nobody
checks in. The ratio of occupied rooms to unoccupied rooms is now 4:5. Use
this information to figure out how many rooms there are in the hotel in all.

$v$ = number occupied

$u$ = number unoccupied

$\frac{v}{u} = \frac{6}{5}$

$5v = 6u$

$\frac{v-230}{u+230} = \frac{4}{5}$

$5v-1150 = 4u+920$

$6u-1150 = 4u+920$

$2u = 2070$

$u = 1035$

finish up and find $v$
