If `x = 2k-1` and `y=k` is a solution the equation `3x-5y-7=0`; find the value of k.

Text Solution

Verified by Experts

Given equation is 3x-5y-7=0
x=2k-1 and y=k is a solution of given equation.
Now, put the values of x and y in given equation:
3(2k-1)-5k-7=0
6k-3-5k-7=0
k=10
`therefore` the value of k is 10.
