Whakaoti i te -12(3-x)=-18

$$- 12 ( 3 - x ) = - 18$$

Whakaoti mō x

$$x = \frac{3}{2} = 1\frac{1}{2} = 1.5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ngā taha e rua ki te -12.

$$3-x=\frac{-18}{-12}$$

Whakahekea te hautanga \frac{-18}{-12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -6.

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

Tangohia te 3 mai i ngā taha e rua.

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

Me tahuri te 3 ki te hautau \frac{6}{2}.

$$-x=\frac{3}{2}-\frac{6}{2}$$

Tā te mea he rite te tauraro o \frac{3}{2} me \frac{6}{2}, me tango rāua mā te tango i ō raua taurunga.

$$-x=\frac{3-6}{2}$$

Tangohia te 6 i te 3, ka -3.

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

Me whakarea ngā taha e rua ki te -1.

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