Whakaoti i te 112x+64(1/2-3x)=2.4

$$112x+64( \frac{ 1 }{ 2 } -3x)=2.4$$

Whakaoti mō x

$$x=0.37$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 64 ki te \frac{1}{2}-3x.

$$112x+64\times \frac{1}{2}-192x=2.4$$

Whakareatia te 64 ki te \frac{1}{2}, ka \frac{64}{2}.

$$112x+\frac{64}{2}-192x=2.4$$

Whakawehea te 64 ki te 2, kia riro ko 32.

$$112x+32-192x=2.4$$

Pahekotia te 112x me -192x, ka -80x.

$$-80x+32=2.4$$

Tangohia te 32 mai i ngā taha e rua.

$$-80x=2.4-32$$

Tangohia te 32 i te 2.4, ka -29.6.

$$-80x=-29.6$$

Whakawehea ngā taha e rua ki te -80.

$$x=\frac{-29.6}{-80}$$

Whakarohaina te \frac{-29.6}{-80} mā te whakarea i te taurunga me te tauraro ki te 10.

$$x=\frac{-296}{-800}$$

Whakahekea te hautanga \frac{-296}{-800} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -8.

$$x=\frac{37}{100}$$
