Question

x + y = k
x - y = k
The solution of the system shown is _____.
(0, k)
(0, 0)
(k, 0)

Answer 1

im not sure it's correct, but by using solving system of equations you should get (k, 0)

Answer 2

(k,o) may be the right answer.

Answer 3

Is that fine to you?

Answer 4

Answer 5

Let's use the reduction method
by adding them up, you'll cancel out the y's, leaving you with x=k

Now if x=k, let's replace k by x
x-y=k
x-y=x
x-x=y
0=y

Since x = k and 0 = y, we'll say that the solution to this system is (K,0)
