\frac{3\left(x-4\right)}{5x\left(x-4\right)}+\frac{4\times 5x}{5x\left(x-4\right)}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Ko te taurea pātahi iti rawa o 5x me x-4 ko 5x\left(x-4\right). Whakareatia \frac{3}{5x} ki te \frac{x-4}{x-4}. Whakareatia \frac{4}{x-4} ki te \frac{5x}{5x}.
\frac{3\left(x-4\right)+4\times 5x}{5x\left(x-4\right)}
Tā te mea he rite te tauraro o \frac{3\left(x-4\right)}{5x\left(x-4\right)} me \frac{4\times 5x}{5x\left(x-4\right)}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{3x-12+20x}{5x\left(x-4\right)}
Mahia ngā whakarea i roto o 3\left(x-4\right)+4\times 5x.
\frac{23x-12}{5x\left(x-4\right)}
Whakakotahitia ngā kupu rite i 3x-12+20x.
\frac{23x-12}{5x^{2}-20x}
Whakarohaina te 5x\left(x-4\right).
