Kua tāruatia ki te papatopenga
x-\frac{3}{20}x=68
Whakahekea te hautanga \frac{15}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
\frac{17}{20}x=68
Pahekotia te x me -\frac{3}{20}x, ka \frac{17}{20}x.
x=68\times \frac{20}{17}
Me whakarea ngā taha e rua ki te \frac{20}{17}, te tau utu o \frac{17}{20}.
x=\frac{68\times 20}{17}
Tuhia te 68\times \frac{20}{17} hei hautanga kotahi.
x=\frac{1360}{17}
Whakareatia te 68 ki te 20, ka 1360.
x=80
Whakawehea te 1360 ki te 17, kia riro ko 80.
