16 years old.

Step-by-step explanation:

Bill is 3 years older than Mike (B=3+M), and Mike is 2 years older than Sisie (M=2+S). Their age altogether now is 25. (B+M+S=25). How old will billy be in 5 years from now?

First of all, let's write our equations.

Where;

b = Bill's age

m = Mike's age

s = Sisie's age

Let's find b in terms of s by replacing m in the first equation.

Now our m and b have the same s variable which makes it easier for us to replace in the third equation to find s.

Now that we've found s, simply replace in Mike's age equation to find his age.

Now replace m in Bill's age equation.

Therefore, Bill is 11 years old, Mike is 8 years old, and Sisie is 6 years old. Altogether, they're 25 years old.

Our question is: How old will bill be in 5 years from now?

If Bill is 11, add 5 = 16 years old.
