Let's denote her younger brother's height as \( x \) inches. According to the problem, Cassandra's height (63 inches) is 6 inches less than three times her younger brother's height. We can translate this information into an equation:
\( 3 \times x \) represents three times her younger brother's height, and since Cassandra is 6 inches less than this value, we can write:
\( 3 \times x - 6 = 63 \)
Now we have an equation that represents the problem statement. To put it into the required form \( px + q = r \), we can simply rewrite it:
\( 3x - 6 = 63 \)
This equation is now in the form \( px + q = r \), where \( p = 3 \), \( q = -6 \), and \( r = 63 \).
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.
