Using a system of equations, it is found that the simplified equation is y = 6x - 5.

  • Ada is x years old.
  • Bill is y years old.

Last year, Ada was x - 1 years old and Bill was y - 1 years old.

Bill was 6 times as old as Ada, hence:

[tex]y - 1 = 6(x - 1)[/tex]

[tex]y - 1 = 6x - 6[/tex]

[tex]y = 6x - 6 + 1[/tex]

[tex]y = 6x - 5[/tex]

The simplified equation is y = 6x - 5.
