(A) x+y=-1
2x-3x=-5

(B) 2x + 5y =-11
4x + 10y = -22

(C) 2x -y=1
3x + 2y = 0

(D) x - 4y -14 = 0
5x-y-13=0
Choose the correct option and explain how..??? ​

Answer 1

A)x+y=-1

B)2x+5y=-11

C)3x+2y=0

D)x-4y-14=0

As in the given linear equations left hand side is equal to right hand side they have an unique solution..................✌✌
