Hi there,
bob is 12 years less than triple als age
B = 3A - 12
if bobs and als age sum to 104 years.
B + A = 104
Replace B with 3A - 12 from top equation.
3A - 12 + A = 104
Collect like terms:
3A + A = 104 + 12
4A = 116
A = 29
Al's age = 29 yrs old
Bob's age = 75 yrs old
Hope this helps :-)

Equations:
b = 3a-12
b + a = 104
------
Substitute for "b" and solve for "a":
3a-12 + a = 104
4a = 116
a = 29 (Al's age now)
----
b = 3a-12 = 75 (Bob's age now)
