The first thing we need to do is to take the important information.
The baseball team played 18 games (=18) They won four games more then they lost. x+4 They have a win to lose ratio, so the x is in half. x/2 the final equation would look like (x/2)+4=18 use pemdas to get the variable by itself. subtract four. 18-4=14 then take that number and divide it by 2. 14/2=7 the amount of games that they won was 11. The amount of games they lst was 7. Hope this helped in the best of your mathematical journey.
