Kua tāruatia ki te papatopenga
x+90=-90x
Tē taea kia ōrite te tāupe x ki -90 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x+90.
x+90+90x=0
Me tāpiri te 90x ki ngā taha e rua.
91x+90=0
Pahekotia te x me 90x, ka 91x.
91x=-90
Tangohia te 90 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-90}{91}
Whakawehea ngā taha e rua ki te 91.
x=-\frac{90}{91}
Ka taea te hautanga \frac{-90}{91} te tuhi anō ko -\frac{90}{91} mā te tango i te tohu tōraro.
