Question 507491
one half of Terri's age is the same as one fourth of Brian's. The sum of their ages is 36. how old is each?
-----
Equations:
(T/2) = B/4
T + B = 36
---
Rearrange:
T = B/2
----
Substitute for "T" and solve for "B":
B/2 + B = 36
(3/2)B = 36
B = (2/3)(36) = 24 yrs (Brian's age now)
----
solve for "T":
T = B/2
T = 12 (Terri's age now)
