Kua tāruatia ki te papatopenga
\frac{1}{9\left(1-x\right)}+1
Tuhia te \frac{\frac{1}{9}}{1-x} hei hautanga kotahi.
\frac{1}{9\left(1-x\right)}+\frac{9\left(1-x\right)}{9\left(1-x\right)}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia 1 ki te \frac{9\left(1-x\right)}{9\left(1-x\right)}.
\frac{1+9\left(1-x\right)}{9\left(1-x\right)}
Tā te mea he rite te tauraro o \frac{1}{9\left(1-x\right)} me \frac{9\left(1-x\right)}{9\left(1-x\right)}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{1+9-9x}{9\left(1-x\right)}
Mahia ngā whakarea i roto o 1+9\left(1-x\right).
\frac{10-9x}{9\left(1-x\right)}
Whakakotahitia ngā kupu rite i 1+9-9x.
\frac{10-9x}{-9x+9}
Whakarohaina te 9\left(1-x\right).
