Kua tāruatia ki te papatopenga
x=\frac{3}{4}-\frac{5}{4}
Tangohia te \frac{5}{4} mai i ngā taha e rua.
x=\frac{3-5}{4}
Tā te mea he rite te tauraro o \frac{3}{4} me \frac{5}{4}, me tango rāua mā te tango i ō raua taurunga.
x=\frac{-2}{4}
Tangohia te 5 i te 3, ka -2.
x=-\frac{1}{2}
Whakahekea te hautanga \frac{-2}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
