Question

2x + y = 8
x - y = 1​

Answer 1

Answer:

2x+y=8

(x,y)=(0,8) ; (x,y)=(2,4)

Step-by-step explanation:

x-y=1

(x,y)=(0,-1) ; (x,y)=(2,1) ; (x,y)= (5,4)

Answer 2

Correct answer

2x+y=8 ----->1

x-y=1 --------->2

》Multiply equation 2 with 2

=>2(x-y=1)

=>2x-2y=2 ----->3

》Subtracting e.q 1 and 3

=> 2x+y=8

-2x-2y=-1

Ans => y=7

》Put value of y in e.q 2

=> x-7=1

=>x=1+7

=>x=8

Hence. x = 8. and. y = 7

Hope so it will help you
