\frac{3\times 4t}{4t\left(2n-5\right)}+\frac{7\left(2n-5\right)}{4t\left(2n-5\right)}
Biex iżżid jew tnaqqas l-espressjonijiet, espandihom biex id-denominaturi tagħhom ikunu l-istess. L-inqas multiplu komuni ta' 2n-5 u 4t huwa 4t\left(2n-5\right). Immultiplika \frac{3}{2n-5} b'\frac{4t}{4t}. Immultiplika \frac{7}{4t} b'\frac{2n-5}{2n-5}.
\frac{3\times 4t+7\left(2n-5\right)}{4t\left(2n-5\right)}
Billi \frac{3\times 4t}{4t\left(2n-5\right)} u \frac{7\left(2n-5\right)}{4t\left(2n-5\right)} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.
