Question 161848: Bob is twice as old as Emma; Kent is 16 years older than Emma; the sum of their ages is 60 years; find the age of each.
Lets translate this into algebra
Your variables will be:
Bob = b
Emma= e
Kent= k
So
b = 2e
k = e + 16
b+e+k=60
you can only solve one equation if it only has one variable; so lets try to work with variable e only:
Since **b=2e and **k=e + 16
then by substitution
b+e+k=60
(2e)+e + (e+16)=60
4e+16=60
4e=44
e=11
Then b=2e=2(11)=22
k=e+16=11+16=27
check:
b+e+k=11+22+37=60
