Question

find tha value of k, if x=2, y=(-1) is a solution of tha equation 2x-3y=k​

Answer 1

K=7

Step-by-step explanation:

x=2,y=-1

2x - 3y =K

2×2 -3 × (-1) = K

4 - (-3) =K

4+3 = K

7 = K

Answer 2

Given equation is 2x-3y=k

According to question x=2,y= -1

Now substituting the values of x and y in the equation 2x+3y=k,we get,

(2×2)-(3×-1)=k

⇒ 4+3=k

⇒ 7=k

So, k = 7

So, the value of k, if x=2,y= -1 is a solution of the equation 2x+3y=k is 7
