Question

If (3,2) is the solution of linear equations 2x - ky + 4 = 0, then the value of k is_
a) -5,
b) 5,
c) -8,
d) 12​

Answer 1

Answer:

k=5

Step-by-step explanation:

(3,2) is a solution of linear equation 2x-ky+4=0

substitute x = 3 and y = 2 in given linear equation

3(2) - 2k + 4 = 0

6 - 2k + 4 = 0

10 -2k = 0

10 = 2k

k = 5
