15-0\times 36-5a=0
Whakareatia te 15 ki te 0, ka 0.
15-0-5a=0
Whakareatia te 0 ki te 36, ka 0.
15-5a=0
Tangohia te 0 i te 15, ka 15.
-5a=-15
Tangohia te 15 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
a=\frac{-15}{-5}
Whakawehea ngā taha e rua ki te -5.
a=3
Whakawehea te -15 ki te -5, kia riro ko 3.
