Kua tāruatia ki te papatopenga
1365\left(x-2\right)=45\times 91+60
Whakareatia ngā taha e rua o te whārite ki te 91.
1365x-2730=45\times 91+60
Whakamahia te āhuatanga tohatoha hei whakarea te 1365 ki te x-2.
1365x-2730=4095+60
Whakareatia te 45 ki te 91, ka 4095.
1365x-2730=4155
Tāpirihia te 4095 ki te 60, ka 4155.
1365x=4155+2730
Me tāpiri te 2730 ki ngā taha e rua.
1365x=6885
Tāpirihia te 4155 ki te 2730, ka 6885.
x=\frac{6885}{1365}
Whakawehea ngā taha e rua ki te 1365.
x=\frac{459}{91}
Whakahekea te hautanga \frac{6885}{1365} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 15.
