Answer 2

I can help you with your math problems. Here is my answer:

The pair of numbers (-1; 3) is a solution of the following equations:

- 2x - 17y = 53 - (x - 3)(x + 2) = -20 - x^2 + 1 = y^2 - 7

To check, you can substitute x = -1 and y = 3 in each equation and see if it is true.

The other equations do not have (-1; 3) as a solution. For example, if you substitute x = -1 and y = 3 in 3x^2 + y^2 = 12, you get 3 + 9 = 12, which is false. Similarly, you can check the other equations and see that they are false for x = -1 and y = 3.Ответь+подробно.++Розв\'язком+яких+рівнянь+є+пара+чисел+(-1;+3):+1)+2x+–+17y+=+53+++2)+3х²+y²+=+123)+(x+-+3)(x+++2)+=+-20+4)+0x++4y+=+-12+5)+0х+++0y+=+0;+6)+х2++1=+y2+–+7​+
