    So if x=a, then y is 3
    5a+3=8
    5a=5
    a=1

    Answer:

    a=1

    Step-by-step explanation:

    Let’s find out!

    So we have the point (x,y)=(a,3) is on the equation 5x+y=8.

    Let’s replace x with a and y with 3. This gives us:

    5x+y=8

    5a+3=8

    Subtract 3 on both sides:

    5a    =5

    Divide both sides by 5:

    a     =5/5

    a     =1

    So the point has to be (1,3)
