Whakaoti i te (x+4%)=7640

$$(x+4 \% )=7640$$

Whakaoti mō x

$$x = \frac{190999}{25} = 7639\frac{24}{25} = 7639.96$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakahekea te hautanga \frac{4}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$x+\frac{1}{25}=7640$$

Tangohia te \frac{1}{25} mai i ngā taha e rua.

$$x=7640-\frac{1}{25}$$

Me tahuri te 7640 ki te hautau \frac{191000}{25}.

$$x=\frac{191000}{25}-\frac{1}{25}$$

Tā te mea he rite te tauraro o \frac{191000}{25} me \frac{1}{25}, me tango rāua mā te tango i ō raua taurunga.

$$x=\frac{191000-1}{25}$$

Tangohia te 1 i te 191000, ka 190999.

$$x=\frac{190999}{25}$$
