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.
