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

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

Whakaoti mō x

$$x=-1$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$2x+2+3\left(x+2\right)=3$$

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

$$2x+2+3x+6=3$$

Pahekotia te 2x me 3x, ka 5x.

$$5x+2+6=3$$

Tāpirihia te 2 ki te 6, ka 8.

$$5x+8=3$$

Tangohia te 8 mai i ngā taha e rua.

$$5x=3-8$$

Tangohia te 8 i te 3, ka -5.

$$5x=-5$$

Whakawehea ngā taha e rua ki te 5.

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

Whakawehea te -5 ki te 5, kia riro ko -1.

$$x=-1$$
