Whakaoti i te 3(y+2)-2(2y-3)=12

$$3 ( y + 2 ) - 2 ( 2 y - 3 ) = 12$$

Whakaoti mō y

$$y=0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$3y+6-2\left(2y-3\right)=12$$

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

$$3y+6-4y+6=12$$

Pahekotia te 3y me -4y, ka -y.

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

Tāpirihia te 6 ki te 6, ka 12.

$$-y+12=12$$

Tangohia te 12 mai i ngā taha e rua.

$$-y=12-12$$

Tangohia te 12 i te 12, ka 0.

$$-y=0$$

He ōrite te hua o ngā tau e rua ki 0 ina 0 tētahi o rāua te iti rawa. Tātemea kāore te -1 e ōrite ki 0, me ōrite pū te y ki 0.

$$y=0$$
