Question

the linear equation 2x + Y is equal to zero and X + Y is equal to 2 have ​

Answer 1

Answer:

the question is 2x+y=0 & X+ y=2

first we have to take the value of x from first equation

so X = -y/2

this value is put in equation first

-y/2+y=2

-y+2y/2=2

on solving y is equal to 4

then this value is put in equation

X=-y/2=-4/2=-2

Answer 2

Question =

2x + y = 0.

x + y = 2

x = 2 - y ( 1 )

Put the value of x in first equation.

2( 2 - y ) + y = 0

4 - 2y + y = 0

y = 4

x = 2 - 4

x = -2
