Kua tāruatia ki te papatopenga
3\times 7+y=21
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
21+y=21
Whakareatia te 3 ki te 7, ka 21.
y=21-21
Tangohia te 21 mai i ngā taha e rua.
y=0
Tangohia te 21 i te 21, ka 0.
x=7 y=0
Kua oti te pūnaha te whakatau.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
