$$\frac{126}{x+y}$$

Passi Qosra tas-Soluzzjonijiet

Biex iżżid jew tnaqqas l-espressjonijiet, espandihom biex id-denominaturi tagħhom ikunu l-istess. L-inqas multiplu komuni ta' y u x+y huwa y\left(x+y\right). Immultiplika \frac{1}{y} b'\frac{x+y}{x+y}. Immultiplika \frac{1}{x+y} b'\frac{y}{y}.

$$\frac{126\left(\frac{x+y}{y\left(x+y\right)}-\frac{y}{y\left(x+y\right)}\right)}{\frac{x}{y}}$$

Billi \frac{x+y}{y\left(x+y\right)} u \frac{y}{y\left(x+y\right)} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.
