wins/games played = .60

wins + 15/gamesplayed+15 = .80

2 equations with 2 unknowns looks doable

hrm. ok! thank you!

amistre64 · Answer

solve for wins from the first one:

wins = gamesplayed * .60

sub that into the 2nd one to have only one variable to deal with

$$\frac{.6g+15}{g+15}=.80$$
