Question

A pair of linear eqhation which has a unique soln of X = 2,Y=-3.
A)x+y=/-1 ; 2x-3y = -5 B) 2x+5y=-11 ; 4x+10y=-22 C)2x-y=1 ; 3x+2y=0
D)x-4y/14 ; 5x-y-13

Answer 1

Answer:

given

x=2 &Y= -3 are solutions of pair of linear equations

substitute X&Y values in option A ,option B, Option C

Option D

therebfour Option c satisfies hence C is correct answer
