After a big snow storm, Joe and Jim decided to shovel driveways for money. Jim shoveled 3 less than twice as many driveways as Joe. They shoveled a total of 15 driveways. How many driveways did Joe and Jim each shovel?
Answer provided by our tutors
Let
x = the number of driveways that Joe shoveled
2x - 3 = the number of driveways that Jim shoveled
Together they shoveled 15 driveways means:
x + (2x - 3) = 15

........
x = 6 driveways
2*6 - 3 = 12 - 3 = 9 driveways
Joe shoveled 6 driveways while Jim shoveled 9 driveways.
