Answer:
solution is (3, - 1)
Step-by-step explanation:
given the 2 equations
x + y = 2 → (1)
x - y = 4 → (2)
Adding the 2 equations term by term will eliminate the y-term
(x + x) + (y - y) = (2 + 4)
2x = 6 ( divide both sides by 2 )
x = 3
substitute x = 3 in either (1) or (2) for y
(1) → 3 + y = 2 ( subtract 3 from both sides )
y = 2 - 3 = - 1
solution is (3, - 1)
