Answer:
If you are asked if a point is a solution to an equation, we replace the variables with the given values and see if the 2 sides of the equation are equal (so is a solution), or not equal (so not a solution). A solution to a system of equations means the point must work in both equations in the system.
Simply divide the 8 cars by the numerator of the fraction 4 to get your answer!
Answer:
<em>If you are asking if that's correct then yes it is</em>
Step-by-step explanation:
2x-y=8...(1)
x+y=7....(2)
from (2)
y=7-x....(3)
put (3) into (1)
2x-(7-x)=8
2x-7+x=8
2x+x=8+7
3x=15
x=5.....(4)
put (4) into (2)
x+y=7
5+y=7
y=7-5
y=2
