Kua tāruatia ki te papatopenga
125x-7000=0.25\times 7000
Tangohia te 4500 i te -2500, ka -7000.
125x-7000=1750
Whakareatia te 0.25 ki te 7000, ka 1750.
125x=1750+7000
Me tāpiri te 7000 ki ngā taha e rua.
125x=8750
Tāpirihia te 1750 ki te 7000, ka 8750.
x=\frac{8750}{125}
Whakawehea ngā taha e rua ki te 125.
x=70
Whakawehea te 8750 ki te 125, kia riro ko 70.
