Kua tāruatia ki te papatopenga
3+x\left(-10\right)=10x+x
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.
3+x\left(-10\right)=11x
Pahekotia te 10x me x, ka 11x.
3+x\left(-10\right)-11x=0
Tangohia te 11x mai i ngā taha e rua.
3-21x=0
Pahekotia te x\left(-10\right) me -11x, ka -21x.
-21x=-3
Tangohia te 3 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-3}{-21}
Whakawehea ngā taha e rua ki te -21.
x=\frac{1}{7}
Whakahekea te hautanga \frac{-3}{-21} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -3.
