You can put this solution on YOUR website! Brian is three times as old as Jordan.
b = 3j
maggie is five years older than Jordan.
m = j+5
If the sum of their ages is 100,
b + j + m = 100
how old are Brian, Jordan, and Maggie
In the above equation, replace b with 3j and replace m with (j+5)
3j + j + (j+5) = 100
5j = 100 - 5
5j = 95
j = 95/5
j = 19 is Jordan's age
:
Use the first two equations to find b and m. See that your 3 solutions add up to 100
