Kua tāruatia ki te papatopenga
-83=-3+18a-8a
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te 1-6a.
-83=-3+10a
Pahekotia te 18a me -8a, ka 10a.
-3+10a=-83
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
10a=-83+3
Me tāpiri te 3 ki ngā taha e rua.
10a=-80
Tāpirihia te -83 ki te 3, ka -80.
a=\frac{-80}{10}
Whakawehea ngā taha e rua ki te 10.
a=-8
Whakawehea te -80 ki te 10, kia riro ko -8.
