Whakaoti i te x-2/4-3x-3/8=x/2

$$\frac { x - 2 } { 4 } - \frac { 3 x - 3 } { 8 } = \frac { x } { 2 }$$

Whakaoti mō x

$$x=-\frac{1}{5}=-0.2$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 8, arā, te tauraro pātahi he tino iti rawa te kitea o 4,8,2.

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

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

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

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

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

Ko te tauaro o -3 ko 3.

$$2x-4-3x+3=4x$$

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

$$-x-4+3=4x$$

Tāpirihia te -4 ki te 3, ka -1.

$$-x-1=4x$$

Tangohia te 4x mai i ngā taha e rua.

$$-x-1-4x=0$$

Pahekotia te -x me -4x, ka -5x.

$$-5x-1=0$$

Me tāpiri te 1 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$-5x=1$$

Whakawehea ngā taha e rua ki te -5.

$$x=\frac{1}{-5}$$

Ka taea te hautanga \frac{1}{-5} te tuhi anō ko -\frac{1}{5} mā te tango i te tohu tōraro.

$$x=-\frac{1}{5}$$
