Question

(c) Ada is x years old and Bill is y years old.

Answer 1

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:

$y - 1 = 6(x - 1)$

$y - 1 = 6x - 6$

$y = 6x - 6 + 1$

$y = 6x - 5$

The simplified equation is y = 6x - 5.
