Whakaoti i te 18-3(x+12)=25x-(x+36)

$$18-3(x+12)=25x-(x+36)$$

Whakaoti mō x

$$x=\frac{2}{3}\approx 0.666666667$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te x+12.

$$18-3x-36=25x-\left(x+36\right)$$

Tangohia te 36 i te 18, ka -18.

$$-18-3x=25x-\left(x+36\right)$$

Hei kimi i te tauaro o x+36, kimihia te tauaro o ia taurangi.

$$-18-3x=25x-x-36$$

Pahekotia te 25x me -x, ka 24x.

$$-18-3x=24x-36$$

Tangohia te 24x mai i ngā taha e rua.

$$-18-3x-24x=-36$$

Pahekotia te -3x me -24x, ka -27x.

$$-18-27x=-36$$

Me tāpiri te 18 ki ngā taha e rua.

$$-27x=-36+18$$

Tāpirihia te -36 ki te 18, ka -18.

$$-27x=-18$$

Whakawehea ngā taha e rua ki te -27.

$$x=\frac{-18}{-27}$$

Whakahekea te hautanga \frac{-18}{-27} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -9.

$$x=\frac{2}{3}$$
