Given => 5x - 2y = k. and (2, -2) is one solution.
So,
x = 2
y = -2
=> 5(2) - 2(-2) = k
=> 10 + 4 = k
=> k = 14
So,
x = 2
y = -2
=> 5(2) - 2(-2) = k
=> 10 + 4 = k
=> k = 14

5x - 2y = k
put x = 2 , y = -2
=> {5 × 2} - {2 × (-2)} = k
=> 10 - (-4) = k
=> 10 +4 = k
=> 14 = k
put x = 2 , y = -2
=> {5 × 2} - {2 × (-2)} = k
=> 10 - (-4) = k
=> 10 +4 = k
=> 14 = k
