Let's say Cassandra's younger brother's height is B inches.
According to the problem, Cassandra's height is 63 inches, which is 6 inches less than 3 times her younger brother's height. So, 3B - 6 = 63.
Therefore, the equation in the form px + q = r is 3B - 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
