Question

Find the value of k, if x=7 and y=-3 is a solution of the equation 4x+3y-k=0. (5)​

Answer 1

Step-by-step explanation:

Given, equation is: 5x+3y−k=0

Putting value of x=3 and y=2 in the above equation, we get

5(3)+3(2)−k=0

or, 15+6−k=0

or, 21−k=0

or, k=21

Answer 2

Answer:

37

Step-by-step explanation:

4x + 3y - k = 0

(4*7) + (3*3) - k = 0

28 + 9 = k

K = 37
