Kua tāruatia ki te papatopenga
\frac{1540\times 18}{3}+120x-35000=0
Tuhia te \frac{1540}{3}\times 18 hei hautanga kotahi.
\frac{27720}{3}+120x-35000=0
Whakareatia te 1540 ki te 18, ka 27720.
9240+120x-35000=0
Whakawehea te 27720 ki te 3, kia riro ko 9240.
-25760+120x=0
Tangohia te 35000 i te 9240, ka -25760.
120x=25760
Me tāpiri te 25760 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{25760}{120}
Whakawehea ngā taha e rua ki te 120.
x=\frac{644}{3}
Whakahekea te hautanga \frac{25760}{120} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 40.
