Equation 1. f = 13s

Equation 2. f + 9 = 4(s + 9) ie f + 9 = 4s + 36 ie f = 4s + 27

Substitute for f: 13s = 4s + 27

Subtract 4s from each side: 9s = 27

Divide each side by 9: s = 3 so f = 39 ( in 9 years s = 12, f = 48)

A father is 32 years old His son is 4 In how many years will the father be three times as old as his son What is the algerbraic equation for that?

The father is always 28 years older than his son so the equation can be written: (1) father = son + 28 at all times after birth at some point father is three times older than son so: (2) father = 3son So we can combine (1) and (2) equations as: 3son = son + 28 2son = 28 son = 14 so when the son is 14 the father is 28 years older which is 42 and 3 times older than 14.

How many years will it be until Mr Walker is 3 times older than his son Mr Walker is 22 years old and his son is 2 years old?

It will take 20 years for Mr Walker to be 3 times older than his son. This is because Mr Walker is currently 20 years older than his son (22 - 2 = 20), and when his son is x years old, Mr Walker will be 3 times older than him (x = 20).


How many years will it be until Mr Walker is 3 times older than his son if Mr. Walker is 22 years old and his son is 2 years old?

He will never reach that exact age.In four years' time they will be 26 and 6 so that Mr Walker will be 4.33... times his son's age, or 3.33... times older than his son. In five years' time they will be 27 and 7 so that Mr Walker will be 3.86... times his son's age, or 2.86... times older than his son.
