If they worked for k hours, the amount of work done would be [tex]\mathbf{ \dfrac{k(x+y)}{xy}}[/tex]hours.

How do we determine the job done using algebraic expressions?

Algebraic expression involves the use of variables and their arithmetic operations.

Given that:

  • Mr. Inwood does a job in x hours, while
  • Mr. Lui can do it in y hours

If we have a function denoted by k (hours) indicating the work they both can do together. Then we can conclude that they can both work for:

[tex]\mathbf{=\dfrac{k}{x}+\dfrac{k}{y}}[/tex]

[tex]\mathbf{ \dfrac{k(x+y)}{xy}}[/tex]
