Kua tāruatia ki te papatopenga
x-\frac{17}{20}x=540
Whakahekea te hautanga \frac{85}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
\frac{3}{20}x=540
Pahekotia te x me -\frac{17}{20}x, ka \frac{3}{20}x.
x=540\times \frac{20}{3}
Me whakarea ngā taha e rua ki te \frac{20}{3}, te tau utu o \frac{3}{20}.
x=\frac{540\times 20}{3}
Tuhia te 540\times \frac{20}{3} hei hautanga kotahi.
x=\frac{10800}{3}
Whakareatia te 540 ki te 20, ka 10800.
x=3600
Whakawehea te 10800 ki te 3, kia riro ko 3600.
