Whakaoti i te {l}{10x-3-text{wiekbabci}}{7x+x+3=10x-3+x-3}

$$\left. \begin{array} { l } { 10 x - 3 - \text { wiek babci } } \\ { 7 x + x + 3 = 10 x - 3 + x - 3 } \end{array} \right.$$

Whakaoti mō x

$$x=3$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Pahekotia te 7x me x, ka 8x.

$$8x+3=10x-3+x-3$$

Pahekotia te 10x me x, ka 11x.

$$8x+3=11x-3-3$$

Tangohia te 3 i te -3, ka -6.

$$8x+3=11x-6$$

Tangohia te 11x mai i ngā taha e rua.

$$8x+3-11x=-6$$

Pahekotia te 8x me -11x, ka -3x.

$$-3x+3=-6$$

Tangohia te 3 mai i ngā taha e rua.

$$-3x=-6-3$$

Tangohia te 3 i te -6, ka -9.

$$-3x=-9$$

Whakawehea ngā taha e rua ki te -3.

$$x=\frac{-9}{-3}$$

Whakawehea te -9 ki te -3, kia riro ko 3.

$$x=3$$
