Question 741602
James is as twice as old as his son. in 20 years their combined ages will be 115 years. how old is his son?
----------
Equations:
j = 2*s
j+20 + s+20 = 115
-------
Substitute for "j" and solve for "s":
-------
2s+20 + s+20 = 115
3s + 40 = 115
3s = 75
son's age = 25
----
James's age = 3s = 75
