If 5x – 3y = k, where x, y ∈ N, x ≥ –2 and y ≤ 1, then the minimum value of k is यदि 5x – 3y = k, जहाँ x, y ∈ N, x ≥ –2 तथा y ≤ 1, तब k का न्यूनतम मान है
If x = 3 and y = 4 is a solutions of the equation 5x - 3y = k, find the value of k.
Find the value of k if x=2,y=1 is a solution, of the equation 2x+3y=k.
