Question

solve for Xand Y 2/x-1 -1/y-1=4 ,4/x-1-1/y-1=10

Answer 1

let 1/X-1=a 1/y-1=b.
2a-b=4+1=5
4a-b=11(10+1)
subtract them
-2a=-6
2a=6
a=6/2=3
b=2a-5=2(3)-5=6-5=1
a=1/x-1=3
3x-3=1
3x=3+1=4
X=4/3
b=1/y-1=1
y-1=1
y=1+1=2

Answer 2

Answer:let 1/X-1=a 1/y-2=b.

2a-b=4+1=5

4a-b=11(10+1)

subtract them

-2a=-6

2a=6

a=6/2=3

b=2a-5=2(3)-5=6-5=1

a=1/x-1=3

3x-3=1

3x=3+1=4

X=4/3

b=1/y-1=1

3y-2=1

3y=1+2=3

y=3/2
