Help improve your chess game
17 more tells us to add 17
Twice as many is telling us to multiply by 2
We'll call
w = games won
L = games lost
w + L = 77 since total games was 77
w = 2L + 17
Substituting this w into the first equation
(2L + 17) + L = 77
3L = 60
L = 20
w = 2L + 17
w = 2(20) + 17
w = 57
