Whakaoti i te 1.5*2+(x-1.5)*2+(x-1.5)*3=10

$$1.5 \times 2 + ( x - 1.5 ) \times 2 + ( x - 1.5 ) \times 3 = 10$$

Whakaoti mō x

$$x=2.9$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 1.5 ki te 2, ka 3.

$$3+\left(x-1.5\right)\times 2+\left(x-1.5\right)\times 3=10$$

Whakamahia te āhuatanga tohatoha hei whakarea te x-1.5 ki te 2.

$$3+2x-3+\left(x-1.5\right)\times 3=10$$

Tangohia te 3 i te 3, ka 0.

$$2x+\left(x-1.5\right)\times 3=10$$

Whakamahia te āhuatanga tohatoha hei whakarea te x-1.5 ki te 3.

$$2x+3x-4.5=10$$

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

$$5x-4.5=10$$

Me tāpiri te 4.5 ki ngā taha e rua.

$$5x=10+4.5$$

Tāpirihia te 10 ki te 4.5, ka 14.5.

$$5x=14.5$$

Whakawehea ngā taha e rua ki te 5.

$$x=\frac{14.5}{5}$$

Whakarohaina te \frac{14.5}{5} mā te whakarea i te taurunga me te tauraro ki te 10.

$$x=\frac{145}{50}$$

Whakahekea te hautanga \frac{145}{50} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$x=\frac{29}{10}$$
