Whakaoti i te -1.5x-3=0.2x+6

$$- 1.5 x - 3 = 0.2 x + 6$$

Whakaoti mō x

$$x = -\frac{90}{17} = -5\frac{5}{17} \approx -5.294117647$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te 0.2x mai i ngā taha e rua.

$$-1.5x-3-0.2x=6$$

Pahekotia te -1.5x me -0.2x, ka -1.7x.

$$-1.7x-3=6$$

Me tāpiri te 3 ki ngā taha e rua.

$$-1.7x=6+3$$

Tāpirihia te 6 ki te 3, ka 9.

$$-1.7x=9$$

Whakawehea ngā taha e rua ki te -1.7.

$$x=\frac{9}{-1.7}$$

Whakarohaina te \frac{9}{-1.7} mā te whakarea i te taurunga me te tauraro ki te 10.

$$x=\frac{90}{-17}$$

Ka taea te hautanga \frac{90}{-17} te tuhi anō ko -\frac{90}{17} mā te tango i te tohu tōraro.

$$x=-\frac{90}{17}$$
