Whakaoti i te -0.7(2x-7)=0.3(11-4x)

$$-0.7(2x-7)=0.3(11-4x)$$

Whakaoti mō x

$$x=8$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te -0.7 ki te 2x-7.

$$-1.4x+4.9=0.3\left(11-4x\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 0.3 ki te 11-4x.

$$-1.4x+4.9=3.3-1.2x$$

Me tāpiri te 1.2x ki ngā taha e rua.

$$-1.4x+4.9+1.2x=3.3$$

Pahekotia te -1.4x me 1.2x, ka -0.2x.

$$-0.2x+4.9=3.3$$

Tangohia te 4.9 mai i ngā taha e rua.

$$-0.2x=3.3-4.9$$

Tangohia te 4.9 i te 3.3, ka -1.6.

$$-0.2x=-1.6$$

Whakawehea ngā taha e rua ki te -0.2.

$$x=\frac{-1.6}{-0.2}$$

Whakarohaina te \frac{-1.6}{-0.2} mā te whakarea i te taurunga me te tauraro ki te 10.

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

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

$$x=8$$
