Question 57347: I am using a practice guide for my SAT's. In it is this problem.
"Erik owned 50 marlbles. After winning w marbles in one game and losing k marbles in the next game, he owned 60 marbles. What is the value of w-k?"
I have tried 50w-k=60, which didn't work out. I tried 50+w-k=60, which also didn't work out. If you can please help me to find the correct way to interpret the problem for solving I would appreciate it. Thanks.

50+w-k=60
w-k=10
