Question

If the point (3, 2) lies on the graph of equltion 5x+ ay =19 then find the value of A write the equation, (match the pairs)

Answer 1

Here , Given :

x = 3

y = 2

To find :

a = ?

equation = 5x+ay =19

Now put the value of x and y .

(5*3) + (a*2) = 19

15 + 2a = 19

2a = 19 - 15

2a = 4

a = 4/2

a = 2

Hence , the value of a is 2.
