Whakaoti i te 3+d=2(3+3+d)+3

$$3 + d = 2 ( 3 + 3 + d ) + 3$$

Whakaoti mō d

$$d=-12$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tāpirihia te 3 ki te 3, ka 6.

$$3+d=2\left(6+d\right)+3$$

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

$$3+d=12+2d+3$$

Tāpirihia te 12 ki te 3, ka 15.

$$3+d=15+2d$$

Tangohia te 2d mai i ngā taha e rua.

$$3+d-2d=15$$

Pahekotia te d me -2d, ka -d.

$$3-d=15$$

Tangohia te 3 mai i ngā taha e rua.

$$-d=15-3$$

Tangohia te 3 i te 15, ka 12.

$$-d=12$$

Me whakarea ngā taha e rua ki te -1.

$$d=-12$$
