Kua tāruatia ki te papatopenga
50+90x=x\times 94
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x.
50+90x-x\times 94=0
Tangohia te x\times 94 mai i ngā taha e rua.
50-4x=0
Pahekotia te 90x me -x\times 94, ka -4x.
-4x=-50
Tangohia te 50 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-50}{-4}
Whakawehea ngā taha e rua ki te -4.
x=\frac{25}{2}
Whakahekea te hautanga \frac{-50}{-4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -2.
