$$88 \% \text { of } 370 + 24 \% \text { of } 210 - x = 118$$

Whakaoti mō x

$$x=258$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakahekea te hautanga \frac{88}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{22}{25}\times 370+\frac{24}{100}\times 210-x=118$$

Tuhia te \frac{22}{25}\times 370 hei hautanga kotahi.

$$\frac{22\times 370}{25}+\frac{24}{100}\times 210-x=118$$

Whakareatia te 22 ki te 370, ka 8140.

$$\frac{8140}{25}+\frac{24}{100}\times 210-x=118$$

Whakahekea te hautanga \frac{8140}{25} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{1628}{5}+\frac{24}{100}\times 210-x=118$$

Whakahekea te hautanga \frac{24}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{1628}{5}+\frac{6}{25}\times 210-x=118$$

Tuhia te \frac{6}{25}\times 210 hei hautanga kotahi.

$$\frac{1628}{5}+\frac{6\times 210}{25}-x=118$$

Whakareatia te 6 ki te 210, ka 1260.

$$\frac{1628}{5}+\frac{1260}{25}-x=118$$

Whakahekea te hautanga \frac{1260}{25} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{1628}{5}+\frac{252}{5}-x=118$$

Tā te mea he rite te tauraro o \frac{1628}{5} me \frac{252}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{1628+252}{5}-x=118$$

Tāpirihia te 1628 ki te 252, ka 1880.

$$\frac{1880}{5}-x=118$$

Whakawehea te 1880 ki te 5, kia riro ko 376.

$$376-x=118$$

Tangohia te 376 mai i ngā taha e rua.

$$-x=118-376$$

Tangohia te 376 i te 118, ka -258.

$$-x=-258$$

Me whakarea ngā taha e rua ki te -1.

$$x=258$$
