Whakaoti i te -4(r+6)=-55

$$- 4 ( r + 6 ) = - 55$$

Whakaoti mō r

$$r = \frac{31}{4} = 7\frac{3}{4} = 7.75$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ngā taha e rua ki te -4.

$$r+6=\frac{-55}{-4}$$

Ka taea te hautanga \frac{-55}{-4} te whakamāmā ki te \frac{55}{4} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.

$$r+6=\frac{55}{4}$$

Tangohia te 6 mai i ngā taha e rua.

$$r=\frac{55}{4}-6$$

Me tahuri te 6 ki te hautau \frac{24}{4}.

$$r=\frac{55}{4}-\frac{24}{4}$$

Tā te mea he rite te tauraro o \frac{55}{4} me \frac{24}{4}, me tango rāua mā te tango i ō raua taurunga.

$$r=\frac{55-24}{4}$$

Tangohia te 24 i te 55, ka 31.

$$r=\frac{31}{4}$$
