Let x be the height of Cassandra's younger brother.
The equation representing this problem is 3x - 6 = 63.
Cassandra measured her height as 63 inches. That is 6 inches less than 3 times her younger brother's height. How tall is her younger brother? Write an equation in the form px + q = r to represent this problem

The 6 was wrong
Apologies for the confusion. Let's correct the equation:
Cassandra measured her height as 63 inches, which is 6 inches less than 3 times her younger brother's height. Let x represent her younger brother's height.
The correct equation is:
3x - 6 = 63
In this equation, 3x represents 3 times her brother's height, and (3x - 6) represents Cassandra's height. We subtract 6 from 3x because Cassandra's height is 6 inches less than 3 times her brother's height.
