Whakaoti i te 2.3x-2(0.7+2x)=3.6-1.7

$$2.3x-2(0.7+2x)=3.6-1.7$$

Whakaoti mō x

$$x = -\frac{33}{17} = -1\frac{16}{17} \approx -1.941176471$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$2.3x-1.4-4x=3.6-1.7$$

Pahekotia te 2.3x me -4x, ka -1.7x.

$$-1.7x-1.4=3.6-1.7$$

Tangohia te 1.7 i te 3.6, ka 1.9.

$$-1.7x-1.4=1.9$$

Me tāpiri te 1.4 ki ngā taha e rua.

$$-1.7x=1.9+1.4$$

Tāpirihia te 1.9 ki te 1.4, ka 3.3.

$$-1.7x=3.3$$

Whakawehea ngā taha e rua ki te -1.7.

$$x=\frac{3.3}{-1.7}$$

Whakarohaina te \frac{3.3}{-1.7} mā te whakarea i te taurunga me te tauraro ki te 10.

$$x=\frac{33}{-17}$$

Ka taea te hautanga \frac{33}{-17} te tuhi anō ko -\frac{33}{17} mā te tango i te tohu tōraro.

$$x=-\frac{33}{17}$$
