Question

A pair of linear equations which has a unique solution x = 5, y = -2 is

3x + y = 1; 2x - 3y = -3

3x + 2y = 11; 2x + 3y = 4

x - y = 1 ; 3x + 2y = 0

2x-4y- 1 = 0; 5x-y- 1 = 0​

Answer 1

Answer:

Here's your answer

Step-by-step explanation:

you have to do this by putting the value of x and y in every equation

so, for unique solution

we have a1/a2 not= to b1/b2

1 . 3x+y=1 and 2x-3y=5

3(5)+(-2)=1 and 2(5)-3(-2)

15/10 Isnotequalto -2/-3

like this you can try the rest of three equations

and you can have the multiple answers in this question

Hope you understand.
