Kua tāruatia ki te papatopenga
\frac{4}{5}+x=\frac{3}{4}
Whakahekea te hautanga \frac{6}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
x=\frac{3}{4}-\frac{4}{5}
Tangohia te \frac{4}{5} mai i ngā taha e rua.
x=\frac{15}{20}-\frac{16}{20}
Ko te maha noa iti rawa atu o 4 me 5 ko 20. Me tahuri \frac{3}{4} me \frac{4}{5} ki te hautau me te tautūnga 20.
x=\frac{15-16}{20}
Tā te mea he rite te tauraro o \frac{15}{20} me \frac{16}{20}, me tango rāua mā te tango i ō raua taurunga.
x=-\frac{1}{20}
Tangohia te 16 i te 15, ka -1.
