Question

find the value of 'k' in x= - 10 and y =2

Answer 1

Answer:

I couldn't understand your question so take a question from webpage but I didn't change the value of x and y, just took the equation, hope you can understand,,

Step-by-step explanation:

4x - ky = 10.

$x = - 10 \: and \: y = 2 \\ 4x - ky = 10 \\ 4 \times ( - 10) - k \times 2 = 10 \\ - 40 - 2k = 10 \\ - 2k = 10 + 40 \\ - 2k = 50 \\ k = - 25$

The value of k is -25.

Hope it will help you,,, ☺
