Two questions about the eighth grade fraction If the solution of the equation 2x + A / X-1 = 1 of X is positive, then the value range of a is? If the fractional equation x-a / x-1-3 / x = 1 for X, then a is equal to? Where (/) denotes the fractional line Supplement: the second problem is that if the fractional equation x-a / x-1-3 / x = 1 about X has no solution, then a is equal to? Where (/) denotes the fractional line
