Question

2x+y =5 ,x+y=4 by elimination method ​

Answer 1

Answer:

x= 1 , y =3

Step-by-step explanation:

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

x+y= 4 ---(2)

/* Subtract equation (2) from equation (1) , we get

2x+y-x-y = 5-4

=> x = 1

/* put x = 1 in equation (2) ,we get

=> 1+y = 4

=> y = 4-1 = 3

Therefore,

x = 1 ,

y = 3

Answer 2

2x + y = 5 , x +y = 4

=> 2x - x+y-y= 5-4

=> x= 1

x ka man 1 rakhne par

x+y= 4

1 + y = 4

y= 4-1

y= 3.

x=1,y=3
