Hello Dear User__________

Here is Your Answer...!!

____________________

Step by step solution:

$Given \ x=2 \ and \ y=-3\\we \ have \ to \ write \ pair \ of \ equation \ which \ has \ a \ unique \ solution \ x=2 \ and \ y=-3\\\\ x-y = 5 \ and \ 2x- y = 7\\\\ for \ unique \ solution \ we \ know \ that\\\\\frac{a1}{a2}\neq\frac{b1}{b2}\\\\putting \ value \ here \ to \ check \ it\\\\\frac{1}{-1} \neq \frac{2}{-1}=-1\neq-2\\\\Hence \ checked.$

Hope it is clear to you.

Answer 2

SOLUTION

The system of equations x-y=5 and 2x-y=7 has the unique solution x=2 and y=-3.

There are infinite pair of system of equations which have the unique solution x=2 and y= -3.

hope it's helps
