Whakaoti i te 25x-2/5+x/5=10x+18

$$25 x - \frac { 2 } { 5 } + \frac { x } { 5 } = 10 x + 18$$

Whakaoti mō x

$$x = \frac{23}{19} = 1\frac{4}{19} \approx 1.210526316$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia ngā taha e rua o te whārite ki te 5.

$$125x-2+x=50x+90$$

Pahekotia te 125x me x, ka 126x.

$$126x-2=50x+90$$

Tangohia te 50x mai i ngā taha e rua.

$$126x-2-50x=90$$

Pahekotia te 126x me -50x, ka 76x.

$$76x-2=90$$

Me tāpiri te 2 ki ngā taha e rua.

$$76x=90+2$$

Tāpirihia te 90 ki te 2, ka 92.

$$76x=92$$

Whakawehea ngā taha e rua ki te 76.

$$x=\frac{92}{76}$$

Whakahekea te hautanga \frac{92}{76} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$x=\frac{23}{19}$$
