Kua tāruatia ki te papatopenga
2x+7=0
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2x=-7
Tangohia te 7 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-7}{2}
Whakawehea ngā taha e rua ki te 2.
x=-\frac{7}{2}
Ka taea te hautanga \frac{-7}{2} te tuhi anō ko -\frac{7}{2} mā te tango i te tohu tōraro.
