Kua tāruatia ki te papatopenga
\frac{7}{5}y=\frac{15}{5}-\frac{1}{5}
Me tahuri te 3 ki te hautau \frac{15}{5}.
\frac{7}{5}y=\frac{15-1}{5}
Tā te mea he rite te tauraro o \frac{15}{5} me \frac{1}{5}, me tango rāua mā te tango i ō raua taurunga.
\frac{7}{5}y=\frac{14}{5}
Tangohia te 1 i te 15, ka 14.
y=\frac{14}{5}\times \frac{5}{7}
Me whakarea ngā taha e rua ki te \frac{5}{7}, te tau utu o \frac{7}{5}.
y=\frac{14\times 5}{5\times 7}
Me whakarea te \frac{14}{5} ki te \frac{5}{7} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
y=\frac{14}{7}
Me whakakore tahi te 5 i te taurunga me te tauraro.
y=2
Whakawehea te 14 ki te 7, kia riro ko 2.
