here is your answer mate.....
Here given (x,y)= (3,5)
just only putting values of x and y in equation.... we get....
3a+5×5=20
3a=20-25=-5
a = -5/3 ans.....

●Since the points (3,5) lie on the graph , they will satisfy the given equation.
✍For finding the value of a so we will as a result substitute the values of the given points in place of x and y.
⤵️⤵️
ax + 5y = 20
=》a(3) + 5(5) = 20
=》 3a = 20 - 25
=》 3a = -5
=》 a = -5/3
●Hence the value of a is -5/3
