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

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

Whakaoti mō x

$$x=\frac{3}{5}=0.6$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$6-2x=3\left(x-4\right)+15$$

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

$$6-2x=3x-12+15$$

Tāpirihia te -12 ki te 15, ka 3.

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

Tangohia te 3x mai i ngā taha e rua.

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

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

$$6-5x=3$$

Tangohia te 6 mai i ngā taha e rua.

$$-5x=3-6$$

Tangohia te 6 i te 3, ka -3.

$$-5x=-3$$

Whakawehea ngā taha e rua ki te -5.

$$x=\frac{-3}{-5}$$

Ka taea te hautanga \frac{-3}{-5} te whakamāmā ki te \frac{3}{5} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.

$$x=\frac{3}{5}$$
