Question 217944
switching x and y ___ x = (3y) / (y - 2)


dividing by x and multiplying by (y - 2) ___ y - 2 = 3y / x


dividing by y ___ 1 - (2 / y) = 3 / x


adding 1 (or x/x) ___ -2 / y = (3 + x) / x


take inverse and multiply by -2 ___ y = -2x / (3 + x)


the domain is all real numbers EXCEPT -3
