You can put this solution on YOUR website! stephanie is 66 years older than Nadia.
s = n + 66
Six years ago, Stephanie was 33 times as old as Nadia
s - 6 = 33(n - 6)
s - 6 = 33n - 198
s = 33n - 198 + 6
s = 33n - 192
replace s with (n+66) from the 1st statement
n + 66 = 33n - 192
n - 33n = -192 - 66
-32n = -258
n = -258/-32
n = +8.0675
How old is Stephannie now?
s = 8.0675 + 66
s = 74.0675; solution should be an integer but I cannot make this problem come out to one.
