Question

Find the value of k for which x = 5, y = 2 is a solution of the equation x + k y = 5​

Answer 1

Answer:

2

Step-by-step explanation:

5+k *2=5

5+k=5-2

5+k= 3

k=5-3

k=2

Answer 2

Given :-

$\sf x + ky = 5$

$\sf x = 5 \\ y = 2$

To find :-

Value of K

Solution :-

$\sf (5) + k(2) = 5$

$\sf 5 + 2k = 5$

$\sf 2k = 5 - 5$

$\sf 2k = 0$

$\sf k = 0$

Procedure :-

→ In this question we need to find the value of k. So we are given the value of x and y too which is 5 and 2.

→ So, we will put 5 in place of x and 2 in place of y then we will equate the whole value. We have put 5-5 because whenever we transpose any constant to another sign it's sign changes.

→ Then we will find the value of k that is 0.
