0.5z+4.1-4.6z=0
Tangohia te 4.6z mai i ngā taha e rua.
-4.1z+4.1=0
Pahekotia te 0.5z me -4.6z, ka -4.1z.
-4.1z=-4.1
Tangohia te 4.1 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
z=\frac{-4.1}{-4.1}
Whakawehea ngā taha e rua ki te -4.1.
z=1
Whakawehea te -4.1 ki te -4.1, kia riro ko 1.
