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 )
