Question

if(2, -1) is the solution of the leniar equation 2x-3y = k then the value of k is​

Answer 1

k=7

Step-by-step explanation:

Given

2x-3y=I

x=2 ,y= -1

2×2-3×(-1)=k

4-(-3)=k

4+3=k

7=k

k=7

Answer 2

Answer:

7

Step-by-step explanation:

let,

x=2, y=. -1

then,

2x-3y=k

substitute x and y values in the given equation

2(2) - 3(-1) = k

4+3=k

k= 7
