A baseball team played 20 games. they won 4 games more than they lost. how many games did they win

Let x represent the amount of games the won

Let y represent the amount of games they lost

x+y=20 (# games won + #games lost = 20 (since they played 20 games))

x=y+4 (# games won = # games lost + 4)

Substituting the second equation into the first equation,

y+4+y=20

2y+4=20

2y=16

y=8

Substituting the y value into the first equation

x+8=20

x=12.

Therefore they won 12 games.
