Kua tāruatia ki te papatopenga
-36-120x-450=0
Tātaihia te 6 mā te pū o 2, kia riro ko 36.
-486-120x=0
Tangohia te 450 i te -36, ka -486.
-120x=486
Me tāpiri te 486 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{486}{-120}
Whakawehea ngā taha e rua ki te -120.
x=-\frac{81}{20}
Whakahekea te hautanga \frac{486}{-120} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 6.
