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)
The commutative property means that the numbers can be switched when multiplying. The second one shows the associative property, where the numbers can be grouped differently. The third one shows the identity property, where multiplying by 1 will get the same number you are multiplying it by. The fourth one shows the zero property, where multiplying by zero will get zero.
Therefore, the answer is the first one because the numbers are simply flipped.
