How do you solve

x-3 / (x-4) + 4 = 3x/3

x - 3 / (x - 4) + 4 = 3 * x/3

x^2-19 / x-4 = x

Step 1: Multiply both sides by x-4.

x^2 - 19 = x^2 - 4x

x^2 - 19 - x^2 = x^2 - 4x - x^2 (Subtract x^2 from both sides)

-19 = - 4x

- 4x = - 19 (Flip the equation)

- 4x / - 4 = - 19 / - 4 (Divide both sides by - 4) Answer.

x = 19/4
