Question

find the value of k if (3,5) is a solution of the equation 2x-ky+4=0

Answer 1

x = 3
y = 5

2*3-k*5+4 = 0
6-5k+4 = 0
10-5k = 0
10 = 5k
2 = k

Answer 2

if (3,5) is the solution so in eq. 2x-ky+4=0 , x=3 and y=4

so substituting x and y in eq. we get

6-4k+4=0

10-4k=0

10=4k

10/4=k

thus k= 5/2
