Two men are playing chess. they play five games and each man won the same number of games with no tie. how is that possible?

It was stated that two men are playing chess but it never mentioned that they were playing with each other. So the two men each won the same number of games in their separate matches. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help. 

1. use commutative property to reorder the terms.2x+81=0.2. move the constant to right side by adding its opposite on both sides. 2x+81-81=0-81.2x=(-81).3. divide the equation on both sides.2x ÷ 2 = 81 ÷ 2.x = -81/2. your answer is -81/2. if you need to simplify it into a decimal, it’s -40.5.
