\frac{1}{7}-3\times \frac{3}{7}n-3\left(-\frac{2}{7}\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te \frac{3}{7}n-\frac{2}{7}.
\frac{1}{7}+\frac{-3\times 3}{7}n-3\left(-\frac{2}{7}\right)
Tuhia te -3\times \frac{3}{7} hei hautanga kotahi.
\frac{1}{7}+\frac{-9}{7}n-3\left(-\frac{2}{7}\right)
Whakareatia te -3 ki te 3, ka -9.
\frac{1}{7}-\frac{9}{7}n-3\left(-\frac{2}{7}\right)
Ka taea te hautanga \frac{-9}{7} te tuhi anō ko -\frac{9}{7} mā te tango i te tohu tōraro.
\frac{1}{7}-\frac{9}{7}n+\frac{-3\left(-2\right)}{7}
Tuhia te -3\left(-\frac{2}{7}\right) hei hautanga kotahi.
\frac{1}{7}-\frac{9}{7}n+\frac{6}{7}
Whakareatia te -3 ki te -2, ka 6.
\frac{1+6}{7}-\frac{9}{7}n
Tā te mea he rite te tauraro o \frac{1}{7} me \frac{6}{7}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{7}{7}-\frac{9}{7}n
Tāpirihia te 1 ki te 6, ka 7.
1-\frac{9}{7}n
Whakawehea te 7 ki te 7, kia riro ko 1.
\frac{1}{7}-3\times \frac{3}{7}n-3\left(-\frac{2}{7}\right)

\frac{1}{7}-\frac{9}{7}n-3\left(-\frac{2}{7}\right)
Ka taea te hautanga \frac{-9}{7} te tuhi anō ko -\frac{9}{7} mā te tango i te tohu tōraro.
\frac{1}{7}-\frac{9}{7}n+\frac{-3\left(-2\right)}{7}
Tuhia te -3\left(-\frac{2}{7}\right) hei hautanga kotahi.
\frac{1}{7}-\frac{9}{7}n+\frac{6}{7}
Whakareatia te -3 ki te -2, ka 6.
\frac{1+6}{7}-\frac{9}{7}n
Tā te mea he rite te tauraro o \frac{1}{7} me \frac{6}{7}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{7}{7}-\frac{9}{7}n
Tāpirihia te 1 ki te 6, ka 7.
1-\frac{9}{7}n
Whakawehea te 7 ki te 7, kia riro ko 1.
