Kua tāruatia ki te papatopenga
720=288+8x+2\times 130
Whakamahia te āhuatanga tohatoha hei whakarea te 36+x ki te 8.
720=288+8x+260
Whakareatia te 2 ki te 130, ka 260.
720=548+8x
Tāpirihia te 288 ki te 260, ka 548.
548+8x=720
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
8x=720-548
Tangohia te 548 mai i ngā taha e rua.
8x=172
Tangohia te 548 i te 720, ka 172.
x=\frac{172}{8}
Whakawehea ngā taha e rua ki te 8.
x=\frac{43}{2}
Whakahekea te hautanga \frac{172}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
