Question

If (3,2) is a solution of equation 3x-KY =5, then find the value of k

Answer 1

Hey

Here is your answer,

Given that,

(3,2) is a solution of the equation 3x -ky=5

so , x = 3 and y = 2

3x - ky = 5
3x3 - kx2 = 5
9-2k=5
-2k = 5-9
-2k = -4
k = -4/-2
k = 2

Hope it helps you!

Answer 2

If (3,2) is a solution of equation 3x - ky = 5 then k = 2

Given :

(3,2) is a solution of equation 3x - ky = 5

To find :

The value of k

Solution :

Step 1 of 2 :

Write down the given equation

Here the given equation is 3x - ky = 5

Step 2 of 2 :

Find the value of k

(3,2) is a solution of equation 3x - ky = 5

So (3,2) satisfies the equation

$\displaystyle \sf{ (3 \times 3) - (k \times 2) = 5 }$

$\displaystyle \sf{ \implies 9- 2k = 5 }$

$\displaystyle \sf{ \implies - 2k = 5 - 9 }$

$\displaystyle \sf{ \implies - 2k = - 4 }$

$\displaystyle \sf{ \implies k = 2}$

Hence the required value of k = 2
