    If x + y = 8 and 2x + y = 10, then what is the value of x?
    Question



    If x + y = 8 and 2x + y = 10, then what is the value of x?

    A.

    2

    B.

    5

    C.

    4

    D.

    6

    Correct option is A


    Given x + y = 8 and 2x + y = 10
    By subtracting equation (1) from equation (2), we can eliminate y.
    (2x+y)−(x+y)=10−8
    2x+y−x−y=2
    x = 2
    Now, substitute x=2 into the first equation to find y.
    2+y=8
    y=6
