Whakaoti i te (x+15%)+20%=7452

$$(x+15 \% )+20 \% =7452$$

Whakaoti mō x

$$x = \frac{149033}{20} = 7451\frac{13}{20} = 7451.65$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakahekea te hautanga \frac{15}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$x+\frac{3}{20}+\frac{20}{100}=7452$$

Whakahekea te hautanga \frac{20}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.

$$x+\frac{3}{20}+\frac{1}{5}=7452$$

Ko te maha noa iti rawa atu o 20 me 5 ko 20. Me tahuri \frac{3}{20} me \frac{1}{5} ki te hautau me te tautūnga 20.

$$x+\frac{3}{20}+\frac{4}{20}=7452$$

Tā te mea he rite te tauraro o \frac{3}{20} me \frac{4}{20}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$x+\frac{3+4}{20}=7452$$

Tāpirihia te 3 ki te 4, ka 7.

$$x+\frac{7}{20}=7452$$

Tangohia te \frac{7}{20} mai i ngā taha e rua.

$$x=7452-\frac{7}{20}$$

Me tahuri te 7452 ki te hautau \frac{149040}{20}.

$$x=\frac{149040}{20}-\frac{7}{20}$$

Tā te mea he rite te tauraro o \frac{149040}{20} me \frac{7}{20}, me tango rāua mā te tango i ō raua taurunga.

$$x=\frac{149040-7}{20}$$

Tangohia te 7 i te 149040, ka 149033.

$$x=\frac{149033}{20}$$
