Whakaoti i te -3=-7/8(-7)+c

$$- 3 = - 7 / 8 ( - 7 ) + c$$

Whakaoti mō c

$$c = -\frac{73}{8} = -9\frac{1}{8} = -9.125$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tuhia te -\frac{7}{8}\left(-7\right) hei hautanga kotahi.

$$-3=\frac{-7\left(-7\right)}{8}+c$$

Whakareatia te -7 ki te -7, ka 49.

$$-3=\frac{49}{8}+c$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$\frac{49}{8}+c=-3$$

Tangohia te \frac{49}{8} mai i ngā taha e rua.

$$c=-3-\frac{49}{8}$$

Me tahuri te -3 ki te hautau -\frac{24}{8}.

$$c=-\frac{24}{8}-\frac{49}{8}$$

Tā te mea he rite te tauraro o -\frac{24}{8} me \frac{49}{8}, me tango rāua mā te tango i ō raua taurunga.

$$c=\frac{-24-49}{8}$$

Tangohia te 49 i te -24, ka -73.

$$c=-\frac{73}{8}$$
