Ninja is 7 years older than is cousin. 2 years ago is was 3 yrs less than twice his age. how old was his cousin then
--------
Equation:
n = c + 7
----
n-2 = 2c-3
----
Substitute for "n" and solve for "c":
c+7-2 = 2c-3
c+5 = 2c-3
c = 8 yrs (cousin's age now)
------
Solve for "n":
n = c+7
n = 15 yrs (Ninja's age now)
