Answer:

(3, - 2 )

Step-by-step explanation:

Given the 2 equations

x + y = 1 → (1)

x - y = 5 → (2)

Adding the 2 equations term by term eliminates y, that is

2x = 6 ( divide both sides by 2 )

x = 3

Substitute x = 3 into either of the 2 equations and solve for y

Substituting into (1)

3 + y = 1 ( subtract 3 from both sides )

y = - 2

Solution is (3, - 2 )
