Question

X + 4 into Y - 2 = X Y and x minus 4 into Y + 4 = x y
by elimination method

Answer 1

(x+4)(y-2)=xy (x-4)(y+4)=xy

xy-2x+4y-8=xy xy+4x-4y-16=xy

2x-4y+8=0 4x-4y-16=0-(eq1)

4y=2x+8 subs in (eq1)

4x+2x+8-16=0

6x=8

X=4/3

Y=(8/3)+8=32/3

Answer 2

equation. With this, I will end up solving an equation with a single variable.
