Whakaoti i te 2*10/2x=(0.6-x)10*3

$$\frac { 2 \cdot 10 } { 2 } x = ( 0.6 - x ) 10 \cdot 3$$

Whakaoti mō x

$$x=0.45$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia ngā taha e rua o te whārite ki te 2.

$$2\times 10x=2\left(0.6-x\right)\times 10\times 3$$

Whakareatia te 2 ki te 10, ka 20.

$$20x=2\left(0.6-x\right)\times 10\times 3$$

Whakareatia te 2 ki te 10, ka 20.

$$20x=20\left(0.6-x\right)\times 3$$

Whakareatia te 20 ki te 3, ka 60.

$$20x=60\left(0.6-x\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 60 ki te 0.6-x.

$$20x=36-60x$$

Me tāpiri te 60x ki ngā taha e rua.

$$20x+60x=36$$

Pahekotia te 20x me 60x, ka 80x.

$$80x=36$$

Whakawehea ngā taha e rua ki te 80.

$$x=\frac{36}{80}$$

Whakahekea te hautanga \frac{36}{80} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$x=\frac{9}{20}$$
