Question

If (3,0) is a solution of the linear equation 4x+y=k then value of k is-

(a) 12 (b) 15 (c) 18 (d) 21
​

Answer 1

Step-by-step explanation:

Given linear equation is

4x+y=k

x=3, y=0

4(3) +0=k

12=k

hence the value of k=12

hope this helps you

Answer 2

Answer:

12

Step-by-step explanation:

(3,0) is a solution of the linear equation 4x+y=k

4(3) + 0 = k

12= k

so the value of k = 12
