Answer 2

Answer:

The value of 'a' is 4 if the point (a,3 ) lies on the graph of the equation 3x +2y =18.

Step-by-step explanation:

If the point (a, 3) lies on 3x + 2y = 18, it must satisfy all conditions for (x, y) = (a, 3).

Therefore,

→ 3(a) + 2(3) = 18

→ 3a + 6 = 18

→ 3a = 18 - 6

→ 3a = 12

→ a = 12/3

→ a = 4

Hence the value of a is 4.
