Kua tāruatia ki te papatopenga
25+x\left(-75\right)=0
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.
x\left(-75\right)=-25
Tangohia te 25 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-25}{-75}
Whakawehea ngā taha e rua ki te -75.
x=\frac{1}{3}
Whakahekea te hautanga \frac{-25}{-75} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -25.
