\frac{12-5}{13}+x=\frac{9}{13}
Tā te mea he rite te tauraro o \frac{12}{13} me \frac{5}{13}, me tango rāua mā te tango i ō raua taurunga.
\frac{7}{13}+x=\frac{9}{13}
Tangohia te 5 i te 12, ka 7.
x=\frac{9}{13}-\frac{7}{13}
Tangohia te \frac{7}{13} mai i ngā taha e rua.
x=\frac{9-7}{13}
Tā te mea he rite te tauraro o \frac{9}{13} me \frac{7}{13}, me tango rāua mā te tango i ō raua taurunga.
x=\frac{2}{13}
Tangohia te 7 i te 9, ka 2.
