Whakaoti i te x*2899-3*2899=4*12256-x*12256

$$x \times 2899 - 3 \times 2899 = 4 \times 12256 - x \times 12256$$

Whakaoti mō x

$$x = \frac{57721}{15155} = 3\frac{12256}{15155} \approx 3.808709997$$

Whakareatia te 3 ki te 2899, ka 8697.

$$x\times 2899-8697=4\times 12256-x\times 12256$$

Whakareatia te 4 ki te 12256, ka 49024.

$$x\times 2899-8697=49024-x\times 12256$$

Me tāpiri te x\times 12256 ki ngā taha e rua.

$$x\times 2899-8697+x\times 12256=49024$$

Pahekotia te x\times 2899 me x\times 12256, ka 15155x.

$$15155x-8697=49024$$

Me tāpiri te 8697 ki ngā taha e rua.

$$15155x=49024+8697$$

Tāpirihia te 49024 ki te 8697, ka 57721.

$$15155x=57721$$

Whakawehea ngā taha e rua ki te 15155.

$$x=\frac{57721}{15155}$$
