Whakaoti i te 2x-1/2=x-2/4-1

$$\frac { 2 x - 1 } { 2 } = \frac { x - 2 } { 4 } - 1$$

Whakaoti mō x

$$x = -\frac{4}{3} = -1\frac{1}{3} \approx -1.333333333$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$2\left(2x-1\right)=x-2-4$$

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 2x-1.

$$4x-2=x-2-4$$

Tangohia te 4 i te -2, ka -6.

$$4x-2=x-6$$

Tangohia te x mai i ngā taha e rua.

$$4x-2-x=-6$$

Pahekotia te 4x me -x, ka 3x.

$$3x-2=-6$$

Me tāpiri te 2 ki ngā taha e rua.

$$3x=-6+2$$

Tāpirihia te -6 ki te 2, ka -4.

$$3x=-4$$

Whakawehea ngā taha e rua ki te 3.

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

Ka taea te hautanga \frac{-4}{3} te tuhi anō ko -\frac{4}{3} mā te tango i te tohu tōraro.

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