Whakaoti i te 2(1-x)+5=3(2x+1)

$$2 ( 1 - x ) + 5 = 3 ( 2 x + 1 )$$

Whakaoti mō x

$$x=\frac{1}{2}=0.5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$2-2x+5=3\left(2x+1\right)$$

Tāpirihia te 2 ki te 5, ka 7.

$$7-2x=3\left(2x+1\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2x+1.

$$7-2x=6x+3$$

Tangohia te 6x mai i ngā taha e rua.

$$7-2x-6x=3$$

Pahekotia te -2x me -6x, ka -8x.

$$7-8x=3$$

Tangohia te 7 mai i ngā taha e rua.

$$-8x=3-7$$

Tangohia te 7 i te 3, ka -4.

$$-8x=-4$$

Whakawehea ngā taha e rua ki te -8.

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

Whakahekea te hautanga \frac{-4}{-8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -4.

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