Step-by-step explanation:
Given
Let
f = Father's age
s = Son's age
We'll solve this question, while reading through the instructions
From the first statement;
f is 2 less than 7 times s.
This means
In two years time, the father will be f +2 and the son will be s + 2
So, their sum is:
Collect like terns
So, the equations are:
Answer: 40x
First, let's find f(2x)
Using this, let's find g(f(2x)):
That's the answer. Let me know if you need any clarifications, thanks!
