Whakaoti i te (400-600x)-65*2=2-200x-15

$$( 400 - 600 x ) - 65 \times 2 = 2 - 200 x - 15$$

Whakaoti mō x

$$x=\frac{283}{400}=0.7075$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 65 ki te 2, ka 130.

$$400-600x-130=2-200x-15$$

Tangohia te 130 i te 400, ka 270.

$$270-600x=2-200x-15$$

Tangohia te 15 i te 2, ka -13.

$$270-600x=-13-200x$$

Me tāpiri te 200x ki ngā taha e rua.

$$270-600x+200x=-13$$

Pahekotia te -600x me 200x, ka -400x.

$$270-400x=-13$$

Tangohia te 270 mai i ngā taha e rua.

$$-400x=-13-270$$

Tangohia te 270 i te -13, ka -283.

$$-400x=-283$$

Whakawehea ngā taha e rua ki te -400.

$$x=\frac{-283}{-400}$$

Ka taea te hautanga \frac{-283}{-400} te whakamāmā ki te \frac{283}{400} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.

$$x=\frac{283}{400}$$
