Kua tāruatia ki te papatopenga
5+2a+8+a=28
Pahekotia te a me a, ka 2a.
13+2a+a=28
Tāpirihia te 5 ki te 8, ka 13.
13+3a=28
Pahekotia te 2a me a, ka 3a.
3a=28-13
Tangohia te 13 mai i ngā taha e rua.
3a=15
Tangohia te 13 i te 28, ka 15.
a=\frac{15}{3}
Whakawehea ngā taha e rua ki te 3.
a=5
Whakawehea te 15 ki te 3, kia riro ko 5.
