Question 955823
Two years ago, John was 3 times as old as Bob. In 5 years time, John will be twice as old as Bob. Find John's present age
------------
Equations:
j-2 = 3(b-2)
j+5 = 2(b+5)
------------
Simplify::
j-3b = -4
j-2b = 5
-----
Substiutute and solve for "b":
3b-4 = 2b+5
b = 9 (bob's age now)
----
solve for "j":
j = 2b+5
j = 18+5 = 23 (john's age now)
