Whakaoti i te 4=-4/3(5)+b

$$4 = - \frac { 4 } { 3 } ( 5 ) + b$$

Whakaoti mō b

$$b = \frac{32}{3} = 10\frac{2}{3} \approx 10.666666667$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tuhia te -\frac{4}{3}\times 5 hei hautanga kotahi.

$$4=\frac{-4\times 5}{3}+b$$

Whakareatia te -4 ki te 5, ka -20.

$$4=\frac{-20}{3}+b$$

Ka taea te hautanga \frac{-20}{3} te tuhi anō ko -\frac{20}{3} mā te tango i te tohu tōraro.

$$4=-\frac{20}{3}+b$$

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

$$-\frac{20}{3}+b=4$$

Me tāpiri te \frac{20}{3} ki ngā taha e rua.

$$b=4+\frac{20}{3}$$

Me tahuri te 4 ki te hautau \frac{12}{3}.

$$b=\frac{12}{3}+\frac{20}{3}$$

Tā te mea he rite te tauraro o \frac{12}{3} me \frac{20}{3}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$b=\frac{12+20}{3}$$

Tāpirihia te 12 ki te 20, ka 32.

$$b=\frac{32}{3}$$
