Question

solutions of x-y=0;2x+y=0 is/ are----------

Answer 1

x - y = 0
so,x=y
solns of x-1,2,3
solns of y-1,2,3

x + y= 0
so,x= -y
solns of x -1,2,3
solns of y- -1,-2,-3

hope u understood my answer.have a good day :D

Answer 2

Add both equation

x-y + 2x+y =0

3x= 0

x=0

x-y = 0

0 = y

y = 0

(x,y)= (0,0)
