Solve for x and y to satisfy both equations in the system:
{6x+y=25}
{2x−3y=25}
x=5, y=−5
The two equations in this system can be combined by addition or subtraction to solve for x and y. Isolate the x variable to solve for it by multiplying the top equation by 3 so that when the equations are combined the y term disappears.
3×(6x+y=25)
→18x+3y=75
→(18x+3y=75)+(2x−3y=25)
→20x=100
Divide both sides by 20 to find 5 as the value for x.
Substituting 5 for x in both of the two equations in the system and solving for y gives a value of −5 for y.

Tom is painting a fence feet long. He starts at the West end of the fence and paints at a rate of feet per hour. After hours, Huck joins Tom and begins painting from the East end of the fence at a rate of feet per hour. After hours of the two boys painting at the same time, Tom leaves Huck to finish the job by himself.
If Huck completes painting the entire fence after Tom leaves, how many more hours will Huck work than Tom?
6 hours
Tom paints for a total of 4 hours (2 on his own, 2 with Huck's help). Since he paints at a rate of 5 feet per hour, use the formula
distance=rate×time (or d=rt)
to determine the total length of the fence Tom paints.
d=(5)(4)
d=20 feet
Subtracting this from the total length of the fence 100 feet gives the length of the fence Tom will NOT paint: 100−20=80 feet. If Huck finishes the job, he will paint that 80 feet of the fence. Using d=rt, we can determine how long this will take Huck to do:
80=8(t)
t=10 hours.
If Huck works 10 hours and Tom works 4 hours, he works 6 more hours than Tom.
