Whakaoti i te 08left(3-xright)-1*2left(x+3*2right)=4

$$08 \left( 3-x \right) -1 \cdot 2 \left( x+3 \cdot 2 \right) = 4$$

Whakaoti mō x

$$x=-8$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 0 ki te 8, ka 0.

$$0\left(3-x\right)-1\times 2\left(x+3\times 2\right)=4$$

Ko te tau i whakarea ki te kore ka hua ko te kore.

$$0-1\times 2\left(x+3\times 2\right)=4$$

Whakareatia te 1 ki te 2, ka 2.

$$0-2\left(x+3\times 2\right)=4$$

Whakareatia te 3 ki te 2, ka 6.

$$0-2\left(x+6\right)=4$$

Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x+6.

$$0-2x-12=4$$

Tangohia te 12 i te 0, ka -12.

$$-12-2x=4$$

Me tāpiri te 12 ki ngā taha e rua.

$$-2x=4+12$$

Tāpirihia te 4 ki te 12, ka 16.

$$-2x=16$$

Whakawehea ngā taha e rua ki te -2.

$$x=\frac{16}{-2}$$

Whakawehea te 16 ki te -2, kia riro ko -8.

$$x=-8$$
