If the point (3, 4) lies on the graph of 3y=ax+7, then find the value of a.

Explanation

Since, the point (x=3, y=4) lies on the equation 3y=ax+7, then the equation will be satisfied by the point .
Now, put x=3 and y=4 in given equation , we get
`3(4) =a (3) +7 implies 12 =3a+7`
`implies " " 3a=12-7 implies 3a=5`
`therefore " " a=(5)/(3)`
Hence, the value of a is `5//3`.
