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:


*if a line is stated to be parallel to another, they will always have the same slope*
*so we can simply go through the answers and find the one with -5x*
