Question

Please tell fast plzzzzzzz​

Answer 1

`\huge\boxed{\sf k = 2}`

Explanation:

Coordinate = (x,y) = (2k-1,k)

This means that:

x = 2k - 1 and y = k

Put it in the given equation: 5x - 4y = 7

5(2k-1) - 4k = 7

10k - 5 - 4k = 7

6k - 5 = 7

Adding 5 to both sides

6k = 7+5

6k = 12

Divide both sides by 6

k = 2

`\rule[225]{225}{2}`

Hope this helped!
