Kua tāruatia ki te papatopenga
2x+9=0
Tātaihia te 3 mā te pū o 2, kia riro ko 9.
2x=-9
Tangohia te 9 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-9}{2}
Whakawehea ngā taha e rua ki te 2.
x=-\frac{9}{2}
Ka taea te hautanga \frac{-9}{2} te tuhi anō ko -\frac{9}{2} mā te tango i te tohu tōraro.
