Kua tāruatia ki te papatopenga
100x-x\times 12\times 5=70000
Whakareatia ngā taha e rua o te whārite ki te 100.
100x-x\times 60=70000
Whakareatia te 12 ki te 5, ka 60.
40x=70000
Pahekotia te 100x me -x\times 60, ka 40x.
x=\frac{70000}{40}
Whakawehea ngā taha e rua ki te 40.
x=1750
Whakawehea te 70000 ki te 40, kia riro ko 1750.
