Plz help me with this

Answer:
You don't even have to graph it.
A) X + Y -6 = 0
B) X - Y = 0
We add the equations and get:
2x -6 = 0
x = 3 and therefore, y = 3
The correct answer is the third answer (3, 3)
Step-by-step explanation:
Answer: (3, 3)
Step-by-step explanation:
Add the equations to eliminate y:
x + y = 6
x - y = 0
2x = 6
÷2 ÷2
x = 3
Substitute x = 3 into either of the equations to solve for y:
x - y = 0
3 - y = 0
3 = y
