3h=7\times \frac{2}{7}+7\left(-\frac{3}{7}\right)h-10
Whakamahia te āhuatanga tohatoha hei whakarea te 7 ki te \frac{2}{7}-\frac{3}{7}h.
3h=2+7\left(-\frac{3}{7}\right)h-10
Me whakakore te 7 me te 7.
3h=2-3h-10
Me whakakore te 7 me te 7.
3h=-8-3h
Tangohia te 10 i te 2, ka -8.
3h+3h=-8
Me tāpiri te 3h ki ngā taha e rua.
6h=-8
Pahekotia te 3h me 3h, ka 6h.
h=\frac{-8}{6}
Whakawehea ngā taha e rua ki te 6.
h=-\frac{4}{3}
Whakahekea te hautanga \frac{-8}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
