Kua tāruatia ki te papatopenga
9^{2}+49\times 9-19=y
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
81+49\times 9-19=y
Tātaihia te 9 mā te pū o 2, kia riro ko 81.
81+441-19=y
Whakareatia te 49 ki te 9, ka 441.
522-19=y
Tāpirihia te 81 ki te 441, ka 522.
503=y
Tangohia te 19 i te 522, ka 503.
y=503
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=9 y=503
Kua oti te pūnaha te whakatau.
