They are different equations lol. If you plug in the same x and y for both you wont get the same answer. Do you have answer choices?
Answer:
a^2 + b^2 =C^2
Step-by-step explanation:
just a hint not a answer
73/4 is the answer to your question sir your welcome
The ordered pair (-1,5) is a solution to the system because it makes both equations true.
1) x+y=4
2) x-y=-6
1) -1 + 5 = 4
5-1 = 4 you can switch the order to make it easier to understand
so
4 = 4
2) -1 - 5 = -6
-1 + -5 = -6 you can change the sign in the middle and make y -
so
-6 = -6
