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.
