Question

Fred is 4 times as old as Nathan and is also 27 years older than Nathan.
Let f be Fred's age and let n be Nathan's age.
Which system of equations represents this situation?
Choose 1 answer:

Answer 1

Answer:

Linear equation of one variable wil be used as it can be expressed in terms of one variable.

Solution:

I can solve it using linear equation of 1 variable :

Let the age of Nathan be x

According to question

4x=x+27

4x-x=27

3x=27

x=27/3

x=9

Age of Fred=9 years

Age of Nathan=4(9) or 9+27

=36 years

Note: This situation represent linear equations of one variable not two
