Let x be the least of the three consecutive old integers.
Since consecutive old integers are 2 away from each other, the next two are and .
Two times the least is then 2x and three times the gretaest is then .
2x exceeds by 15 which means the difference of 2x and is equal to 15.
Distribute the -3 to x and 4.
Combine the like terms of 2x and -3x on the left side.
Add 12 on both sides.
Multiply both sides by -1.
Find the order two old integers by substituing in into and .
Results: -27, -25, and -23
