Question 1036466
Ishaan is 2 times as old as Christopher. 35 years ago, Ishaan was 7 times as old as Christopher.
How old is Ishaan now?
-------------
I = 2*C
I-35 = 7(C-35)
-------
Substitute for "I" and solve for "C"::
2C - 35 = 7C - 245
5C = 210
C = 42 yrs (Christopher's age now)
Ishanna's age now = 2C = 84 yrs
