Whakaoti i te 0.3(0.2x+1)=0.4(0.5x-1)

$$0.3 ( 0.2 x + 1 ) = 0.4 ( 0.5 x - 1 )$$

Whakaoti mō x

$$x=5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 0.3 ki te 0.2x+1.

$$0.06x+0.3=0.4\left(0.5x-1\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 0.4 ki te 0.5x-1.

$$0.06x+0.3=0.2x-0.4$$

Tangohia te 0.2x mai i ngā taha e rua.

$$0.06x+0.3-0.2x=-0.4$$

Pahekotia te 0.06x me -0.2x, ka -0.14x.

$$-0.14x+0.3=-0.4$$

Tangohia te 0.3 mai i ngā taha e rua.

$$-0.14x=-0.4-0.3$$

Tangohia te 0.3 i te -0.4, ka -0.7.

$$-0.14x=-0.7$$

Whakawehea ngā taha e rua ki te -0.14.

$$x=\frac{-0.7}{-0.14}$$

Whakarohaina te \frac{-0.7}{-0.14} mā te whakarea i te taurunga me te tauraro ki te 100.

$$x=\frac{-70}{-14}$$

Whakawehea te -70 ki te -14, kia riro ko 5.

$$x=5$$
