Question

Find the value of k if x = 4 and y = 2 is a solution of the equation 5 x + 4 y = k​

Answer 1

Answer:

5x+4y=k

⇒5(4)+4(−2)=k

⇒k=20−16=4

Answer 2

Step-by-step explanation:

5 x + 4 y = k is a equation

put x value 4 and y value 2 in this equation

5(4) + 4(2) = K

20 + 8 = k

28 = k

hence the value of k is 28
