Whakaoti i te 3left(3-xright)+9=2(x-4)+6

$$3 \left( 3-x \right) +9=2(x-4)+6$$

Whakaoti mō x

$$x=4$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 3-x.

$$9-3x+9=2\left(x-4\right)+6$$

Tāpirihia te 9 ki te 9, ka 18.

$$18-3x=2\left(x-4\right)+6$$

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-4.

$$18-3x=2x-8+6$$

Tāpirihia te -8 ki te 6, ka -2.

$$18-3x=2x-2$$

Tangohia te 2x mai i ngā taha e rua.

$$18-3x-2x=-2$$

Pahekotia te -3x me -2x, ka -5x.

$$18-5x=-2$$

Tangohia te 18 mai i ngā taha e rua.

$$-5x=-2-18$$

Tangohia te 18 i te -2, ka -20.

$$-5x=-20$$

Whakawehea ngā taha e rua ki te -5.

$$x=\frac{-20}{-5}$$

Whakawehea te -20 ki te -5, kia riro ko 4.

$$x=4$$
