Learn how to solve numerical value of an algebraic expression problems step by step online. Find the numerical value of the expression (x-4.0)/(x^2-3.0x+-4.0);x=3.99. Calculate the numerical value for \frac{x-4}{x^2-3x-4} when x=3.99. Replace the unknowns with their corresponding values. Subtract the values 3.99 and -4. Multiply -3 times 3.99. Subtract the values -11.97 and -4.
