Kua tāruatia ki te papatopenga
\frac{12}{7}y=6
Pahekotia te \frac{5}{7}y me y, ka \frac{12}{7}y.
y=6\times \frac{7}{12}
Me whakarea ngā taha e rua ki te \frac{7}{12}, te tau utu o \frac{12}{7}.
y=\frac{6\times 7}{12}
Tuhia te 6\times \frac{7}{12} hei hautanga kotahi.
y=\frac{42}{12}
Whakareatia te 6 ki te 7, ka 42.
y=\frac{7}{2}
Whakahekea te hautanga \frac{42}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 6.
