Kua tāruatia ki te papatopenga
\frac{1540\times 15}{3}+120x-35000=0
Tuhia te \frac{1540}{3}\times 15 hei hautanga kotahi.
\frac{23100}{3}+120x-35000=0
Whakareatia te 1540 ki te 15, ka 23100.
7700+120x-35000=0
Whakawehea te 23100 ki te 3, kia riro ko 7700.
-27300+120x=0
Tangohia te 35000 i te 7700, ka -27300.
120x=27300
Me tāpiri te 27300 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{27300}{120}
Whakawehea ngā taha e rua ki te 120.
x=\frac{455}{2}
Whakahekea te hautanga \frac{27300}{120} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 60.
