Kua tāruatia ki te papatopenga
\frac{3}{2}=\frac{4\times 2}{3}+b
Tuhia te \frac{4}{3}\times 2 hei hautanga kotahi.
\frac{3}{2}=\frac{8}{3}+b
Whakareatia te 4 ki te 2, ka 8.
\frac{8}{3}+b=\frac{3}{2}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
b=\frac{3}{2}-\frac{8}{3}
Tangohia te \frac{8}{3} mai i ngā taha e rua.
b=\frac{9}{6}-\frac{16}{6}
Ko te maha noa iti rawa atu o 2 me 3 ko 6. Me tahuri \frac{3}{2} me \frac{8}{3} ki te hautau me te tautūnga 6.
b=\frac{9-16}{6}
Tā te mea he rite te tauraro o \frac{9}{6} me \frac{16}{6}, me tango rāua mā te tango i ō raua taurunga.
b=-\frac{7}{6}
Tangohia te 16 i te 9, ka -7.
