D) -4​

Answer 1

Question⤵

▶ If (5,K) is a solution of 2x+y-6=0, then the value of ‘k’ is equal to

A) 6

B) 4

C) -3

D) -4

Solution⤵

Given :- (5,K) is a solution of 2x+y-6=0

it means that 5 = x and k = y

solution ⤵

$x = 5 \: and \: y = k \\ 2x + y - 6 = 0 \\ 2 \times 5 + (k) - 6 = 0 \\ 10 + k - 6 = 0 \\ 4 + k = 0 \\ k = - 4$

Answer⤵

▶ D) -4

Here your answer

Answer 2

Answer:

option D)

Step-by-step explanation:

2x+y-6=0

given point (5,K) , means x=5,y=K

applying in equation

2(5)+K-6=0

10+K=6

K=6-10

=-4

therefore K=-4
