\frac{3\times 4\left(x+y\right)}{4\left(x+4\right)\left(x+y\right)}-\frac{3z\left(x+4\right)}{4\left(x+4\right)\left(x+y\right)}

Da biste zbrojili ili oduzeli izraze, proširite ih da bi imali iste nazivnike. Najmanji zajednički višekratnik brojeva x+4 i 4\left(x+y\right) jest 4\left(x+4\right)\left(x+y\right). Pomnožite \frac{3}{x+4} i \frac{4\left(x+y\right)}{4\left(x+y\right)}. Pomnožite \frac{3z}{4\left(x+y\right)} i \frac{x+4}{x+4}.

\frac{3\times 4\left(x+y\right)-3z\left(x+4\right)}{4\left(x+4\right)\left(x+y\right)}

Budući da \frac{3\times 4\left(x+y\right)}{4\left(x+4\right)\left(x+y\right)} i \frac{3z\left(x+4\right)}{4\left(x+4\right)\left(x+y\right)} imaju isti nazivnik, oduzmite ih oduzimanje njihovih brojnika.

\frac{12x+12y-3zx-12z}{4\left(x+4\right)\left(x+y\right)}

Pomnožite izraz 3\times 4\left(x+y\right)-3z\left(x+4\right).
