Question

X + y = k

x - y = k

The solution to the system shown is _____.

(0, k)
(2, 2)
(k, 0)

Answer 1

The answer would be (k,0)

k is the x and 0 is the y

Step-by-step explanation: Use 2 in place of k for an example and plug it in

2+0=2

2-0=2

Answer 2

x + y = k
x - y = k Add these two equations.
2x = 2k Divide both sides by 2
2x/2 = 2k/2
x = k

x + y = k
k + y = k Subtract k from both sides.
y = 0
