Whakaoti i te 3(2x+4)=+2(x+15)

$$3(2x+4)=+2(x+15)$$

Whakaoti mō x

$$x = \frac{9}{2} = 4\frac{1}{2} = 4.5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2x+4.

$$6x+12=2\left(x+15\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+15.

$$6x+12=2x+30$$

Tangohia te 2x mai i ngā taha e rua.

$$6x+12-2x=30$$

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

$$4x+12=30$$

Tangohia te 12 mai i ngā taha e rua.

$$4x=30-12$$

Tangohia te 12 i te 30, ka 18.

$$4x=18$$

Whakawehea ngā taha e rua ki te 4.

$$x=\frac{18}{4}$$

Whakahekea te hautanga \frac{18}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x=\frac{9}{2}$$
