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)
