Question

if the point (3 ,5 )line on the graph of the equation ax + 5y=20 find the value of a.​

Answer 1

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.....

Answer 2

●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
