Whakaoti i te 3.6(x+16)div1.2=1.5

$$3.6(x+16) \div 1.2=1.5$$

Whakaoti mō x

$$x=-15.5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua ki te 1.2.

$$3.6\left(x+16\right)=1.5\times 1.2$$

Whakamahia te āhuatanga tohatoha hei whakarea te 3.6 ki te x+16.

$$3.6x+57.6=1.5\times 1.2$$

Whakareatia te 1.5 ki te 1.2, ka 1.8.

$$3.6x+57.6=1.8$$

Tangohia te 57.6 mai i ngā taha e rua.

$$3.6x=1.8-57.6$$

Tangohia te 57.6 i te 1.8, ka -55.8.

$$3.6x=-55.8$$

Whakawehea ngā taha e rua ki te 3.6.

$$x=\frac{-55.8}{3.6}$$

Whakarohaina te \frac{-55.8}{3.6} mā te whakarea i te taurunga me te tauraro ki te 10.

$$x=\frac{-558}{36}$$

Whakahekea te hautanga \frac{-558}{36} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 18.

$$x=-\frac{31}{2}$$
