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

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

Whakaoti mō x

$$x = \frac{16}{5} = 3\frac{1}{5} = 3.2$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$6x-3-2\left(x+5\right)=-\left(x-3\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x+5.

$$6x-3-2x-10=-\left(x-3\right)$$

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

$$4x-3-10=-\left(x-3\right)$$

Tangohia te 10 i te -3, ka -13.

$$4x-13=-\left(x-3\right)$$

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

$$4x-13=-x-\left(-3\right)$$

Ko te tauaro o -3 ko 3.

$$4x-13=-x+3$$

Me tāpiri te x ki ngā taha e rua.

$$4x-13+x=3$$

Pahekotia te 4x me x, ka 5x.

$$5x-13=3$$

Me tāpiri te 13 ki ngā taha e rua.

$$5x=3+13$$

Tāpirihia te 3 ki te 13, ka 16.

$$5x=16$$

Whakawehea ngā taha e rua ki te 5.

$$x=\frac{16}{5}$$
