Whakaoti i te 3-6y=-6+18y/2

$$3 - 6 y = \frac { - 6 + 18 y } { 2 }$$

Whakaoti mō y

$$y=\frac{2}{5}=0.4$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$6-12y=-6+18y$$

Tangohia te 18y mai i ngā taha e rua.

$$6-12y-18y=-6$$

Pahekotia te -12y me -18y, ka -30y.

$$6-30y=-6$$

Tangohia te 6 mai i ngā taha e rua.

$$-30y=-6-6$$

Tangohia te 6 i te -6, ka -12.

$$-30y=-12$$

Whakawehea ngā taha e rua ki te -30.

$$y=\frac{-12}{-30}$$

Whakahekea te hautanga \frac{-12}{-30} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -6.

$$y=\frac{2}{5}$$
