5 wins and 10 losses

Explanation:

Let the number of wins be #x# and the number of losses be #y#.

Assuming there were no ties,the total number of games played by team would be equal to sum of number of losses and number of wins.

Therefore, (1) #x+y=15 #
Also,the team won 15 more than three times as many games as they lost.
Thus,(2) #3x=15+3y#

Equations (1) and (2) are linear equations in variables #x# and #y#
and can be solved by method of substitution.

From (1) ,#x=15-y#

Substituting #x=15-y # in (2),
#3(15-y)=15+3y#
#45-3y=15+3y#
#45-15=3y+3y#
#30=6y#
Therefore,#y=5#

From (1),#x=15-y#
Substituting #y=5# in above equation,
#x=15-5#
Thus, #x=10#

Thus, the team had 10 wins and 5 losses.
