Question

if (2K-1,K) is a solution of the equation 10x-9y=12. then K=

Answer 1

Heya!!

Given that, (2K-1,K) is a solution of the equation 10x-9y=12.

Now, 10(2k-1) - 9(k) = 12
20k - 10 - 9k = 12
20k - 9k = 12 + 10
11k = 22
k = 22/11
k = 2

Hence, the value of k is 2.

Answer 2

Given,

(2K-1,K) is a solution of the equation 10x-9y=12

To Find,

K =?

Solution,

We can solve the question as follows:

It is given to us that (2K-1, K) is a solution of the equation 10x-9y=12. This means that the given set of points satisfies the equation.

Here,

$(x, y) = (2K-1, K)$

We will substitute the above values in the equation and find K.

$10x - 9y = 12$

$10(2K - 1) -9K = 12$

$20K - 10 - 9K = 12$

$11K - 10 = 12$

$11K = 22$

$K = \frac{22}{11}$

$K = 2$

Hence, the value of K is equal to 2.
