Answer 1

Question:

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

Answer:

k = 10

Step-by-step explanation:

Given a linear equation such that,

3x - 5y - 7 = 0

Also,

The solutions are given as,

x = 2k - 1

y = k

To find the value if k.

Substituting these values, we get,

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

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

=> k - 10 = 0

=> k = 10

Hence, required value of k = 10.
