6) Bill is three times older than Kevin. He is also 28 years older than Kevin. How old are they?

If bill is 28 years older than him, but also 3 times older than him, then you divide 28 by 3, which gives you 9.3. So that means kevin is around 9 1/4 years old and bill is around 37 and 1/4 years old, but you dont ahve to count the fraction if you dont want to, all that matters is the whole number.

Bill is 42, while Kevin is 14 years old

Represent Bill's age with B, and Kevin's age with K.

So, we have the following equations

B = 3K and B = 28 + K

Substitute 3K for B in the second equation

[tex]3K = 28 + K[/tex]

Collect like terms

[tex]-K + 3K = 28[/tex]

[tex]2K = 28[/tex]

Divide both sides by 2

[tex]K = 14[/tex]

Substitute 14 for K in the first equation

[tex]B =3 \times 14[/tex]

[tex]B =42[/tex]

Hence, Bill is 42, while Kevin is 14 years old
