To solve the equation (3x)/(x+1) = 12/(x-1), we can cross-multiply to eliminate the fractions. This gives us 3x(x-1) = 12(x+1). Expanding both sides of the equation, we get 3x^2 - 3x = 12x + 12. Rearranging the terms, we have 3x^2 - 15x - 12 = 0. To solve this quadratic equation, we can factor it or use the quadratic formula. Factoring, we have (x-4)(3x+1) = 0. Setting each factor equal to zero, we get x-4 = 0 or 3x+1 = 0. Solving these equations, we find x = 4 or x = -1/3. Therefore, the solutions to the equation are x = 4 and x = -1/3.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
