Start with -3x + 2 = -7
Subtract 2 from each side
-3x = -9
Divide each side by -3
x = 3
I believe the answer is 14
Answer: The team's win-loss record that year is 1.7
Step-by-step explanation:
During the 2017 Major League Baseball season the Cleveland Indians played 162 games.
Let x = the number of games that the
Cleveland Indians lost during the 2017 Major League Baseball season.
This means that the number of games that the Cleveland Indians won during the 2017 Major League Baseball season would be x + 42.
Total number of games played = sum of games won + sum of games lost. This is expressed as
162 = x + 42 + x
2x + 42 = 162
2x = 162-42 = 120
x = 120/2 = 60
Number of games that the Cleveland Indians lost during the 2017 Major League Baseball season is 60
The number of games that the Cleveland Indians won during the 2017 Major League Baseball season is 60 + 42 = 102
The team's win-loss record that year
would be wins/loses
= 102/60 = 1.7
is symmetric if 
. We have
is indeed symmetric.
