Whakaoti i te -2(x-1)=-[4-3(x-1)]

$$- 2 ( x - 1 ) = - [ 4 - 3 ( x - 1 ) ]$$

Whakaoti mō x

$$x = \frac{9}{5} = 1\frac{4}{5} = 1.8$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x-1.

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

Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te x-1.

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

Tāpirihia te 4 ki te 3, ka 7.

$$-2x+2=-\left(7-3x\right)$$

Hei kimi i te tauaro o 7-3x, kimihia te tauaro o ia taurangi.

$$-2x+2=-7-\left(-3x\right)$$

Ko te tauaro o -3x ko 3x.

$$-2x+2=-7+3x$$

Tangohia te 3x mai i ngā taha e rua.

$$-2x+2-3x=-7$$

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

$$-5x+2=-7$$

Tangohia te 2 mai i ngā taha e rua.

$$-5x=-7-2$$

Tangohia te 2 i te -7, ka -9.

$$-5x=-9$$

Whakawehea ngā taha e rua ki te -5.

$$x=\frac{-9}{-5}$$

Ka taea te hautanga \frac{-9}{-5} te whakamāmā ki te \frac{9}{5} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.

$$x=\frac{9}{5}$$
