Let x represent the height of Cassandra's younger brother.

Since Cassandra measured her height as 63 inches, this can be represented as 63.

According to the problem, Cassandra's height is 6 inches less than 3 times her younger brother's height. This can be expressed as 3x - 6.

Putting it all together, the equation in the form px + q = r to represent this problem is:

3x - 6 = 63
