Kua tāruatia ki te papatopenga
16+x\times 2=-6x
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.
16+x\times 2+6x=0
Me tāpiri te 6x ki ngā taha e rua.
16+8x=0
Pahekotia te x\times 2 me 6x, ka 8x.
8x=-16
Tangohia te 16 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-16}{8}
Whakawehea ngā taha e rua ki te 8.
x=-2
Whakawehea te -16 ki te 8, kia riro ko -2.
