x-4=x-4
Variable x cannot be equal to any of the values -1,4 since division by zero is not defined. Multiply both sides of the equation by \left(x-4\right)\left(x+1\right), the least common multiple of \left(x-4\right)\left(x+1\right),x+1.
x\in \mathrm{C}
This is true for any x.
x\in \mathrm{C}\setminus -1,4
Variable x cannot be equal to any of the values -1,4.
