Whakaoti i te x=12+2-65/8

$$x=12+2 \frac{ -65 }{ 8 }$$

Whakaoti mō x

$$x = -\frac{17}{4} = -4\frac{1}{4} = -4.25$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Ka taea te hautanga \frac{-65}{8} te tuhi anō ko -\frac{65}{8} mā te tango i te tohu tōraro.

$$x=12+2\left(-\frac{65}{8}\right)$$

Tuhia te 2\left(-\frac{65}{8}\right) hei hautanga kotahi.

$$x=12+\frac{2\left(-65\right)}{8}$$

Whakareatia te 2 ki te -65, ka -130.

$$x=12+\frac{-130}{8}$$

Whakahekea te hautanga \frac{-130}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x=12-\frac{65}{4}$$

Me tahuri te 12 ki te hautau \frac{48}{4}.

$$x=\frac{48}{4}-\frac{65}{4}$$

Tā te mea he rite te tauraro o \frac{48}{4} me \frac{65}{4}, me tango rāua mā te tango i ō raua taurunga.

$$x=\frac{48-65}{4}$$

Tangohia te 65 i te 48, ka -17.

$$x=-\frac{17}{4}$$

Tautapa x

$$x≔-\frac{17}{4}$$
