Whakaoti i te 4(x+3)-4=8(2x+2)

$$4(x+3)-4=8(2x+2)$$

Whakaoti mō x

$$x=-\frac{2}{3}\approx -0.666666667$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x+3.

$$4x+12-4=8\left(2x+2\right)$$

Tangohia te 4 i te 12, ka 8.

$$4x+8=8\left(2x+2\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te 2x+2.

$$4x+8=16x+16$$

Tangohia te 16x mai i ngā taha e rua.

$$4x+8-16x=16$$

Pahekotia te 4x me -16x, ka -12x.

$$-12x+8=16$$

Tangohia te 8 mai i ngā taha e rua.

$$-12x=16-8$$

Tangohia te 8 i te 16, ka 8.

$$-12x=8$$

Whakawehea ngā taha e rua ki te -12.

$$x=\frac{8}{-12}$$

Whakahekea te hautanga \frac{8}{-12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$x=-\frac{2}{3}$$
