Whakaoti i te (x*.045*1)+((x*2)*.05*1)=2900

$$(x \times .045 \times 1)+((x \times 2) \times .05 \times 1)=2900$$

Whakaoti mō x

$$x=20000$$

Whakareatia te 0.045 ki te 1, ka 0.045.

$$x\times 0.045+x\times 2\times 0.05\times 1=2900$$

Whakareatia te 2 ki te 0.05, ka 0.1.

$$x\times 0.045+x\times 0.1\times 1=2900$$

Whakareatia te 0.1 ki te 1, ka 0.1.

$$x\times 0.045+x\times 0.1=2900$$

Pahekotia te x\times 0.045 me x\times 0.1, ka 0.145x.

$$0.145x=2900$$

Whakawehea ngā taha e rua ki te 0.145.

$$x=\frac{2900}{0.145}$$

Whakarohaina te \frac{2900}{0.145} mā te whakarea i te taurunga me te tauraro ki te 1000.

$$x=\frac{2900000}{145}$$

Whakawehea te 2900000 ki te 145, kia riro ko 20000.

$$x=20000$$
