Whakaoti i te 5.4x-2.7=4(3.6x+5.4)

$$5.4 x - 2.7 = 4 ( 3.6 x + 5.4 )$$

Whakaoti mō x

$$x=-2.7$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 3.6x+5.4.

$$5.4x-2.7=14.4x+21.6$$

Tangohia te 14.4x mai i ngā taha e rua.

$$5.4x-2.7-14.4x=21.6$$

Pahekotia te 5.4x me -14.4x, ka -9x.

$$-9x-2.7=21.6$$

Me tāpiri te 2.7 ki ngā taha e rua.

$$-9x=21.6+2.7$$

Tāpirihia te 21.6 ki te 2.7, ka 24.3.

$$-9x=24.3$$

Whakawehea ngā taha e rua ki te -9.

$$x=\frac{24.3}{-9}$$

Whakarohaina te \frac{24.3}{-9} mā te whakarea i te taurunga me te tauraro ki te 10.

$$x=\frac{243}{-90}$$

Whakahekea te hautanga \frac{243}{-90} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 9.

$$x=-\frac{27}{10}$$
