Question 1162825
I need help please!

Khalid is 56 years old. Cathleen is 6 years older
than Brody. The sum of Cathleen’s and Brody’s
ages is half Khalid’s age. How old is Cathleen?
<pre>Let Cathleen's age, be C
Then Brody's is: C - 6
We then get: {{{matrix(3,3, C + C - 6, "=", (1/2) * 56, 2C - 6, "=", 28, 2C, "=", 34)}}}
Cathleen, or {{{highlight_green(matrix(1,6, C, "=", 34/2, "=", 17, years-old))}}}
