Question

What are the coefficients of x and y respectively in the equation 5x - y = 10.
IF (2,0) is a solution of linear equation 2x + 3y - k = 0, find the value of k.​

Answer 1

Answer:

k=4

Step-by-step explanation:

The coefficients of x and y are 5 and -1 respectively.

2x+3y-k=0

x=2 and y=0..........(given)

thus, substituting the values of x and y in the linear equation

2(2)+3(0)-k=0

4+0-k=0

4-k=0

-k=-4

therefore, k=4.

hence the value of k is 4.
