Whakaoti i te (x-4.5)*9.8-0.15*10*9.8=(10+4.5+x)*2.2

$$(x-4.5) \times 9.8-0.15 \times 10 \times 9.8=(10+4.5+x) \times 2.2$$

Whakaoti mō x

$$x = \frac{907}{76} = 11\frac{71}{76} \approx 11.934210526$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te x-4.5 ki te 9.8.

$$9.8x-44.1-0.15\times 10\times 9.8=\left(10+4.5+x\right)\times 2.2$$

Whakareatia te 0.15 ki te 10, ka 1.5.

$$9.8x-44.1-1.5\times 9.8=\left(10+4.5+x\right)\times 2.2$$

Whakareatia te 1.5 ki te 9.8, ka 14.7.

$$9.8x-44.1-14.7=\left(10+4.5+x\right)\times 2.2$$

Tangohia te 14.7 i te -44.1, ka -58.8.

$$9.8x-58.8=\left(10+4.5+x\right)\times 2.2$$

Tāpirihia te 10 ki te 4.5, ka 14.5.

$$9.8x-58.8=\left(14.5+x\right)\times 2.2$$

Whakamahia te āhuatanga tohatoha hei whakarea te 14.5+x ki te 2.2.

$$9.8x-58.8=31.9+2.2x$$

Tangohia te 2.2x mai i ngā taha e rua.

$$9.8x-58.8-2.2x=31.9$$

Pahekotia te 9.8x me -2.2x, ka 7.6x.

$$7.6x-58.8=31.9$$

Me tāpiri te 58.8 ki ngā taha e rua.

$$7.6x=31.9+58.8$$

Tāpirihia te 31.9 ki te 58.8, ka 90.7.

$$7.6x=90.7$$

Whakawehea ngā taha e rua ki te 7.6.

$$x=\frac{90.7}{7.6}$$

Whakarohaina te \frac{90.7}{7.6} mā te whakarea i te taurunga me te tauraro ki te 10.

$$x=\frac{907}{76}$$
