Question

solve the x,y by elimination methos 1/x+1+1/y+1 and 1/x+1-1/y+1=4​

Answer 1

Answer:

Step-by-step explanation:

1/x+1+1/y+1=0

1/x+1/y=2

Let 1/x=a

1/y=b

a+b=2 .......1

1/x+1-1/y+1 =4

a-b =4........2

From equation 1 and 2

a+b=2

a-b=4

2a=6

a=3

Put a=3 in equation 1

a+b =2

3+b=2

b=2-3

b=-1
