Question

The value of k if x= 2 k-1 and y=k is the solution of equation
3x-5y-7=0

Answer 1

Answer:

value of k = 10

Step-by-step explanation:

Given Linear equation in two variables x and y :

3x-5y-7 = 0 ---(1)

Substitute x = 2k-1 and y=k in equation (1) , we get

3(2k-1)-5(k)-7=0

=> 6k-3-5k-7=0

=> 6k-5k-3-7=0

=> k-10=0

=> k = 10

Therefore,

value of k = 10

Answer 2

Given values -- x = 2k-1 and y = k

Substitute x = 2k-1 and y=k in equation (1) , we get --

3(2k-1)-5(k)-7=0

= 6k-3-5k-7=0

= 6k-5k-3-7=0

= k-10=0

= k = 10
