Kua tāruatia ki te papatopenga
x-\frac{8}{9}=-\frac{1}{15}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=-\frac{1}{15}+\frac{8}{9}
Me tāpiri te \frac{8}{9} ki ngā taha e rua.
x=-\frac{3}{45}+\frac{40}{45}
Ko te maha noa iti rawa atu o 15 me 9 ko 45. Me tahuri -\frac{1}{15} me \frac{8}{9} ki te hautau me te tautūnga 45.
x=\frac{-3+40}{45}
Tā te mea he rite te tauraro o -\frac{3}{45} me \frac{40}{45}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
x=\frac{37}{45}
Tāpirihia te -3 ki te 40, ka 37.
