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.

Box x + Box= Box
Let's denote her younger brother's height as x (in inches).
According to the information:
Cassandra's height = 3 times her brother's height - 6 inches
Cassandra's height is given as 63 inches, so:
63 = 3x - 6
Now we can reorganize this expression to fit the form px + q = r:
3x - 6 = 63
Here:
p = 3 (the multiplier for the brother's height x)
q = -6 (the amount subtracted from the triple of the brother's height)
r = 63 (Cassandra's actual height)
So the equation in the form px + q = r is:
3x - 6 = 63
