Tohaina
Kua tāruatia ki te papatopenga
100x+18x=1700
Whakaarohia te whārite tuatahi. Whakareatia ngā taha e rua o te whārite ki te 100.
118x=1700
Pahekotia te 100x me 18x, ka 118x.
x=\frac{1700}{118}
Whakawehea ngā taha e rua ki te 118.
x=\frac{850}{59}
Whakahekea te hautanga \frac{1700}{118} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
x=\frac{850}{59} y=40 z=40
Kua oti te pūnaha te whakatau.
