Kua tāruatia ki te papatopenga
x\left(16-0x\right)-120=0
Whakareatia te 0 ki te 5, ka 0.
x\left(16-0\right)-120=0
Ko te tau i whakarea ki te kore ka hua ko te kore.
x\times 16-120=0
Tangohia te 0 i te 16, ka 16.
x\times 16=120
Me tāpiri te 120 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{120}{16}
Whakawehea ngā taha e rua ki te 16.
x=\frac{15}{2}
Whakahekea te hautanga \frac{120}{16} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 8.
