Whakaoti i te 3(x-2)=4(-x+3)

$$3(x-2)=4(-x+3)$$

Whakaoti mō x

$$x = \frac{18}{7} = 2\frac{4}{7} \approx 2.571428571$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

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

Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te -x+3.

$$3x-6=4\left(-x\right)+12$$

Tangohia te 4\left(-x\right) mai i ngā taha e rua.

$$3x-6-4\left(-x\right)=12$$

Whakareatia te -1 ki te 4, ka -4.

$$3x-6-4\left(-1\right)x=12$$

Whakareatia te -4 ki te -1, ka 4.

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

Pahekotia te 3x me 4x, ka 7x.

$$7x-6=12$$

Me tāpiri te 6 ki ngā taha e rua.

$$7x=12+6$$

Tāpirihia te 12 ki te 6, ka 18.

$$7x=18$$

Whakawehea ngā taha e rua ki te 7.

$$x=\frac{18}{7}$$
