Tohaina
Kua tāruatia ki te papatopenga
x=2+4i-4i
Whakaarohia te whārite tuarua. Tangohia te 4i mai i ngā taha e rua.
x=2
Tangohia te 4i i te 2+4i, ka 2.
2+\left(2+y\right)i=2-i
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
2+2i+iy=2-i
Whakamahia te āhuatanga tohatoha hei whakarea te 2+y ki te i.
2i+iy=2-i-2
Tangohia te 2 mai i ngā taha e rua.
2i+iy=-i
Tangohia te 2 i te 2-i, ka -i.
iy=-i-2i
Tangohia te 2i mai i ngā taha e rua.
iy=-3i
Tangohia te 2i i te -i, ka -3i.
y=\frac{-3i}{i}
Whakawehea ngā taha e rua ki te i.
y=-3
Whakawehea te -3i ki te i, kia riro ko -3.
x=2 y=-3
Kua oti te pūnaha te whakatau.
