Verified Answer
The value of k if x = 2, y = 1 is a solution of equation 2x – k = – 3y...
If x = 2, y = 1 is a solution of the equation 2x + 3y = k, then these values will satisfy the equation. So, putting x = 2 and y = 1 in the equation, we get
2(2) + 3(1) = k
⇒ 4 + 3 = k
⇒ k = 7.

As.
2x+3y. (x=2 , y=1)
=2×2 +3×1
=4+3
=7
【k=7】
