Question

The softball team won 70% of its games and won 4 more than it lost. How many games did the team lose?

Answer 1

`3`

Explanation:

The statement can be turned into equations which can then be solved.
If `x` is the number of games lost, and `y` the number of games won, then

`y=x+4`
and
`y=70/100*(x+y)=7/10(x+y)`

`10y=7x+7y`
`3y=7x`
`:.y=7/3x`

Substituting into the first equation gives
`7/3x=x+4`
`7x=3x+12`
`4x=12`
`:.x=3`
