Question

David is $8$ years younger than Michael. If Michael's present age is $x$ years, then the algebraic expression for David's present age (in years) is

• A. $x+8$
• B. $x-8$
• C. $-8x$

Answer 1

The correct option is B $x-8$

Given:
Michael's present age is $x$ years.

David is $8$ years younger than Michael.

So, David's present age = Michael's age - $8$ years

$\therefore$ David's present age (in years) = $x-8$

$\therefore$ $x-8$ years is the algebraic expression for David's present age.
