n represent the number of games lost, write an equation for:
a) A team won three times as many games as it lost. It played a total of 52 years.
b) A team won 20 games more than it lost. It played a total of 84 games.
c) A team won 15 games less than twice the number lost. It played a total of 78 games.
Assuming "years" means "games," the first equation will be:
n + 3n = 52
With this solution, you should be able to generalize to provide the rremaining two equations.
I hope this helps. Thanks for asking.
