3️⃣ -1, 4
4️⃣ 2, 3​

Answer 1

Answer:

2,3 is the answer

Step-by-step explanation:

please mark me as brain lest

Answer 2

x - y = -1 (equation 1)

3x + 2y = 12 (equation 2)

x - y = -1

x = -1 + y

Putting the value of "x" in equation 2

3(-1 + y) + 2y = 12

-3 + 3y + 2y = 12

5y = 15

y = 3

Therefore x = 2
