Kua tāruatia ki te papatopenga
5x-15=\frac{90}{19}\times 8
Me whakarea ngā taha e rua ki te 8.
5x-15=\frac{90\times 8}{19}
Tuhia te \frac{90}{19}\times 8 hei hautanga kotahi.
5x-15=\frac{720}{19}
Whakareatia te 90 ki te 8, ka 720.
5x=\frac{720}{19}+15
Me tāpiri te 15 ki ngā taha e rua.
5x=\frac{720}{19}+\frac{285}{19}
Me tahuri te 15 ki te hautau \frac{285}{19}.
5x=\frac{720+285}{19}
Tā te mea he rite te tauraro o \frac{720}{19} me \frac{285}{19}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
5x=\frac{1005}{19}
Tāpirihia te 720 ki te 285, ka 1005.
x=\frac{\frac{1005}{19}}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{1005}{19\times 5}
Tuhia te \frac{\frac{1005}{19}}{5} hei hautanga kotahi.
x=\frac{1005}{95}
Whakareatia te 19 ki te 5, ka 95.
x=\frac{201}{19}
Whakahekea te hautanga \frac{1005}{95} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
