Answer:
The labor fee is $14.25, each quart of oil costs $2.25.
Step-by-step explanation:
Let $x be thee price of each quart of oil and $y be a flat fee for labor.
1. If the oil change for one car required 5 quarts of oil, then these 5 quarts cost $5x and together with a flat fee for labor it cost $25.50. Thus,
5x+y=25.50.
2. If the oil change for another car required 7 quarts of oil, then these 7 quarts cost $7x and together with a flat fee for labor it cost $30.00. Thus,
7x+y=30.00.
3. Subtract from the second equation the first one, then

Substitute it into the first equation:

The labor fee is $14.25, each quart of oil costs $2.25.
7.2 feet equals 219.456 centimeters
Answer:
x = 5
y = 5
Step-by-step explanation:
In this question you need to solve one equation in order to plug the value into the second one and solve it as well. Lets start with the top one...
2x - x = 5
1x = 5
x = 5
Now we plug that value of x into the second equation
4x - 2y = 10
4(5) - 2y = 10
20 - 2y = 10
-2y = -10
y = 5
Finally, we can see that both x and y have a value of 5.
