Whakaoti i te 2(2x-1)-1=3*2x+2

$$2(2x-1)-1=3 \times 2x+2$$

Whakaoti mō x

$$x = -\frac{5}{2} = -2\frac{1}{2} = -2.5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$4x-2-1=3\times 2x+2$$

Tangohia te 1 i te -2, ka -3.

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

Whakareatia te 3 ki te 2, ka 6.

$$4x-3=6x+2$$

Tangohia te 6x mai i ngā taha e rua.

$$4x-3-6x=2$$

Pahekotia te 4x me -6x, ka -2x.

$$-2x-3=2$$

Me tāpiri te 3 ki ngā taha e rua.

$$-2x=2+3$$

Tāpirihia te 2 ki te 3, ka 5.

$$-2x=5$$

Whakawehea ngā taha e rua ki te -2.

$$x=\frac{5}{-2}$$

Ka taea te hautanga \frac{5}{-2} te tuhi anō ko -\frac{5}{2} mā te tango i te tohu tōraro.

$$x=-\frac{5}{2}$$
