\frac{2k+5}{2}
Tohaina
Kua tāruatia ki te papatopenga
k-\frac{1}{2}+\frac{6}{2}
Me tahuri te 3 ki te hautau \frac{6}{2}.
k+\frac{-1+6}{2}
Tā te mea he rite te tauraro o -\frac{1}{2} me \frac{6}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
k+\frac{5}{2}
Tāpirihia te -1 ki te 6, ka 5.
\frac{2k+5}{2}
Tauwehea te \frac{1}{2}.
2k+5
Whakaarohia te 2k-1+6. Whakarea ka paheko i ngā kīanga tau ōrite.
\frac{2k+5}{2}
Me tuhi anō te kīanga whakatauwehe katoa.
