Whakaoti i te 0.6(x+300)=0.65x-205

$$0.6 ( x + 300 ) = 0.65 x - 205$$

Whakaoti mō x

Whakamahia te āhuatanga tohatoha hei whakarea te 0.6 ki te x+300.

$$0.6x+180=0.65x-205$$

Tangohia te 0.65x mai i ngā taha e rua.

$$0.6x+180-0.65x=-205$$

Pahekotia te 0.6x me -0.65x, ka -0.05x.

$$-0.05x+180=-205$$

Tangohia te 180 mai i ngā taha e rua.

$$-0.05x=-205-180$$

Tangohia te 180 i te -205, ka -385.

$$-0.05x=-385$$

Whakawehea ngā taha e rua ki te -0.05.

$$x=\frac{-385}{-0.05}$$

Whakarohaina te \frac{-385}{-0.05} mā te whakarea i te taurunga me te tauraro ki te 100.

$$x=\frac{-38500}{-5}$$

Whakawehea te -38500 ki te -5, kia riro ko 7700.

$$x=7700$$
