jim is 2 years older than 3 times his little brother. Together their ages add up to 18. how old is each?
----------------------------
Equations:
j = 3b+2
j + b = 18
-----
Substitute for "j" and solve for "b":
3b+2 + b = 18
4b = 16
b = 4 (Brother's age)
------
Solve for "j":
j + 4 = 18
j = 14 years (Jim's age)
