Question 242474: Ok, I need some help...Here we go: Mark is 10 years younger than Larry. Larry's age in 8 years will exceed twice Mark's age 3 years ago by 4 years. How old is each now? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Mark is 10 years younger than Larry. Larry's age in 8 years will exceed twice Mark's age 3 years ago by 4 years. How old is each now?
--------------
NOW DATA:
Let Mark be "M" yrs. old
Let Larry be "L" yrs. old
-----------------------------------
Equations:
M = L -10
(L+8) = 2(M-3)+4
-----------------------------
Substitute for "M" and solve for "L":
L+8 = 2(L-10-3)+3
L+8 = 2L--23
L = 31 (Larry's age NOW)
----------------
Since M = L-10, M = 21 (Mark's age NOW)
==========================================
