Whakaoti i te -2(y+3)=4y-1+2(6y+2)

$$- 2 ( y + 3 ) = 4 y - 1 + 2 ( 6 y + 2 )$$

Whakaoti mō y

$$y=-\frac{1}{2}=-0.5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te y+3.

$$-2y-6=4y-1+2\left(6y+2\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 6y+2.

$$-2y-6=4y-1+12y+4$$

Pahekotia te 4y me 12y, ka 16y.

$$-2y-6=16y-1+4$$

Tāpirihia te -1 ki te 4, ka 3.

$$-2y-6=16y+3$$

Tangohia te 16y mai i ngā taha e rua.

$$-2y-6-16y=3$$

Pahekotia te -2y me -16y, ka -18y.

$$-18y-6=3$$

Me tāpiri te 6 ki ngā taha e rua.

$$-18y=3+6$$

Tāpirihia te 3 ki te 6, ka 9.

$$-18y=9$$

Whakawehea ngā taha e rua ki te -18.

$$y=\frac{9}{-18}$$

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

$$y=-\frac{1}{2}$$
