For this case we can propose a rule of three according to the Shontaro base performance.
4 hits ------------> 12 times at bat
x -------------------> 36 times at bat
Where "x" represents the number of hits he will have the following week, based on his previous performance.

So, Shintaro will have 12 hits in 36 times at bat

y = x + 9 ( in years)
Step-by-step explanation:

If his brother is y years old then
y = x + 9
Since y is the subject, y has been expressed in terms of x. Where y is the age of Patrick's brother and x is Patrick's age.
