Cassandra measured her height as 63 inches.That is 6 inches less than 3 times her younger brothers.how tall is her younger brother

Answer 1

Let h be the height of Cassandra's younger brother.
We know that 63 = 3h - 6.
Adding 6 to both sides, we get 69 = 3h.
Dividing both sides by 3, we get h = 23.
Therefore, Cassandra's younger brother is 23 inches tall.
