9. It is known that the solution of the fractional equation a + 2 / x + 1 = 1 about X is a non positive number? "The answer is a is less than or equal to - 1 and not equal to - 2" My question is: If a = - 1, The equation is 1 / x + 1 = 1, The result of solving the fractional equation is x = - 1 So x + 1 = 0, The fractional equation is meaningless Why is a less than or equal to - 1? That's meaningless
