Kua tāruatia ki te papatopenga
32j-1736=7j+64
Whakareatia ngā taha e rua o te whārite ki te 8.
32j-1736-7j=64
Tangohia te 7j mai i ngā taha e rua.
25j-1736=64
Pahekotia te 32j me -7j, ka 25j.
25j=64+1736
Me tāpiri te 1736 ki ngā taha e rua.
25j=1800
Tāpirihia te 64 ki te 1736, ka 1800.
j=\frac{1800}{25}
Whakawehea ngā taha e rua ki te 25.
j=72
Whakawehea te 1800 ki te 25, kia riro ko 72.
