Kua tāruatia ki te papatopenga
2142=1764\left(x-1\right)
Whakareatia te 42 ki te 42, ka 1764.
2142=1764x-1764
Whakamahia te āhuatanga tohatoha hei whakarea te 1764 ki te x-1.
1764x-1764=2142
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
1764x=2142+1764
Me tāpiri te 1764 ki ngā taha e rua.
1764x=3906
Tāpirihia te 2142 ki te 1764, ka 3906.
x=\frac{3906}{1764}
Whakawehea ngā taha e rua ki te 1764.
x=\frac{31}{14}
Whakahekea te hautanga \frac{3906}{1764} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 126.
