Let's represent Cassandra's height as "x" and her younger brother's height as "y". According to the problem, Cassandra's height is 63 inches, which is 6 inches less than 3 times her brother's height.
So, we can write the equation:
3y - 6 = x
Therefore, the equation in the form px + q = r is:
3y - x = 6
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.
