Whakaoti i te .05=.03(x)+.02(8000+x)

$$.05 = .03 ( x ) + .02 ( 8000 + x )$$

Whakaoti mō x

$$x=-3199$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 0.02 ki te 8000+x.

$$0.05=0.03x+160+0.02x$$

Pahekotia te 0.03x me 0.02x, ka 0.05x.

$$0.05=0.05x+160$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$0.05x+160=0.05$$

Tangohia te 160 mai i ngā taha e rua.

$$0.05x=0.05-160$$

Tangohia te 160 i te 0.05, ka -159.95.

$$0.05x=-159.95$$

Whakawehea ngā taha e rua ki te 0.05.

$$x=\frac{-159.95}{0.05}$$

Whakarohaina te \frac{-159.95}{0.05} mā te whakarea i te taurunga me te tauraro ki te 100.

$$x=\frac{-15995}{5}$$

Whakawehea te -15995 ki te 5, kia riro ko -3199.

$$x=-3199$$
