Kua tāruatia ki te papatopenga
2x+2=0
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
2x=-2
Tangohia te 2 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-2}{2}
Whakawehea ngā taha e rua ki te 2.
x=-1
Whakawehea te -2 ki te 2, kia riro ko -1.
x=-1 y=2
Kua oti te pūnaha te whakatau.
Ngā Tauira
whārite tapawhā
