Kua tāruatia ki te papatopenga
75x+189=7\times 3+1
Whakareatia ngā taha e rua o te whārite ki te 3.
75x+189=21+1
Whakareatia te 7 ki te 3, ka 21.
75x+189=22
Tāpirihia te 21 ki te 1, ka 22.
75x=22-189
Tangohia te 189 mai i ngā taha e rua.
75x=-167
Tangohia te 189 i te 22, ka -167.
x=\frac{-167}{75}
Whakawehea ngā taha e rua ki te 75.
x=-\frac{167}{75}
Ka taea te hautanga \frac{-167}{75} te tuhi anō ko -\frac{167}{75} mā te tango i te tohu tōraro.
