Answer:


f = 7s -2


f + s =53

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


f = 7s -2

In two years time, the father will be f +2 and the son will be s + 2

So, their sum is:


(f+2) + (s + 2) = 57


f + 2 + s + 2 =57

Collect like terns


f + s =57-2-2


f + s =53

So, the equations are:


f = 7s -2


f + s =53
