2x+1=0
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2x=-1
Tangohia te 1 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-1}{2}
Whakawehea ngā taha e rua ki te 2.
x=-\frac{1}{2}
Ka taea te hautanga \frac{-1}{2} te tuhi anō ko -\frac{1}{2} mā te tango i te tohu tōraro.
