Whakaoti i te 0.22x-0.03(95-x)=5.9

$$0.22 x - 0.03 ( 95 - x ) = 5.9$$

Whakaoti mō x

$$x=35$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te -0.03 ki te 95-x.

$$0.22x-2.85+0.03x=5.9$$

Pahekotia te 0.22x me 0.03x, ka 0.25x.

$$0.25x-2.85=5.9$$

Me tāpiri te 2.85 ki ngā taha e rua.

$$0.25x=5.9+2.85$$

Tāpirihia te 5.9 ki te 2.85, ka 8.75.

$$0.25x=8.75$$

Whakawehea ngā taha e rua ki te 0.25.

$$x=\frac{8.75}{0.25}$$

Whakarohaina te \frac{8.75}{0.25} mā te whakarea i te taurunga me te tauraro ki te 100.

$$x=\frac{875}{25}$$

Whakawehea te 875 ki te 25, kia riro ko 35.

$$x=35$$
