Kua tāruatia ki te papatopenga
18+x\left(-15\right)=29x
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.
18+x\left(-15\right)-29x=0
Tangohia te 29x mai i ngā taha e rua.
18-44x=0
Pahekotia te x\left(-15\right) me -29x, ka -44x.
-44x=-18
Tangohia te 18 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-18}{-44}
Whakawehea ngā taha e rua ki te -44.
x=\frac{9}{22}
Whakahekea te hautanga \frac{-18}{-44} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -2.
