The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
Divide both parts of the equation by (-x + x*y)/y
We get the answer: y = 1
x*y-x = 0
Divide both parts of the equation by (-x + x*y)/y
y = 0 / ((-x + x*y)/y)
We get the answer: y = 1
