Question

solve for k if x=1andy=2 : 5kx-7y=k​

Answer 1

Answer:

k = 7/2

Step-by-step explanation:

according to question : x = 1, y = 2

5k*1 - 7*2 = k

5k - 14 = k

5k - k = 14

4k = 14

k = 14/4

k = 7/2

Answer 2

Answer:

given

X = 1 and y = 2

5kx -7y= k

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

5k -14 = k

5k-k=14

4k = 14

k = 14/4

k = 7/2
