Question

Find the value of k if x=3 and y=2 is a solution of the equation 4x + (k -1) y =16.

Answer 1

4(3)+k(2)-2=16

12+2k-2=16

10+2k=16

2k=6

k=3

Answer 2

Answer:

Step-by-step explanation:

4x +(k-1)y = 16

4(3) + y (k-1) = 16

12 + 2 (k-1) = 16

12 + 2k - 2 = 16

10 - 2k = 16

-2k = 16 - 10

-2k = 6

-k = 6/2

-k = 3

now the(-) will on that side

k = -3
