4060x+17400-4640x=0
Tangohia te 4640x mai i ngā taha e rua.
-580x+17400=0
Pahekotia te 4060x me -4640x, ka -580x.
-580x=-17400
Tangohia te 17400 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-17400}{-580}
Whakawehea ngā taha e rua ki te -580.
x=30
Whakawehea te -17400 ki te -580, kia riro ko 30.
