Kua tāruatia ki te papatopenga
9+x\left(-9\right)=27x
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.
9+x\left(-9\right)-27x=0
Tangohia te 27x mai i ngā taha e rua.
9-36x=0
Pahekotia te x\left(-9\right) me -27x, ka -36x.
-36x=-9
Tangohia te 9 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-9}{-36}
Whakawehea ngā taha e rua ki te -36.
x=\frac{1}{4}
Whakahekea te hautanga \frac{-9}{-36} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -9.
