Question

Answer this I’m elimination using addition and subtraction form

Answer 1

Answer:

(0,-4)

Step-by-step explanation:

x-y = 4

2x+y = -4

Add these together to eliminate y

x-y = 4

2x+y = -4

-------------------

3x = 0

Divide by 3

3x/3 = 0/3

x = 0

Now we need to find t

2x+y = -4

0+y = -4

y= -4

Answer 2

Answer:

Step-by-step explanation:

first flip the signs of one of them

4=-2x-y

x-y=4

then set them equal to each other and solve down

x - y = -2x - y

-y = -3x -y

-2y = -3x
