Kua tāruatia ki te papatopenga
28\sqrt{9}-16a=8\times 43
Me whakarea ngā taha e rua ki te 43.
28\times 3-16a=8\times 43
Tātaitia te pūtakerua o 9 kia tae ki 3.
84-16a=8\times 43
Whakareatia te 28 ki te 3, ka 84.
84-16a=344
Whakareatia te 8 ki te 43, ka 344.
-16a=344-84
Tangohia te 84 mai i ngā taha e rua.
-16a=260
Tangohia te 84 i te 344, ka 260.
a=\frac{260}{-16}
Whakawehea ngā taha e rua ki te -16.
a=-\frac{65}{4}
Whakahekea te hautanga \frac{260}{-16} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
