Whakaoti i te 4=2/3(8)-b

$$4 = \frac { 2 } { 3 } ( 8 ) - b$$

Whakaoti mō b

$$b = \frac{4}{3} = 1\frac{1}{3} \approx 1.333333333$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tuhia te \frac{2}{3}\times 8 hei hautanga kotahi.

$$4=\frac{2\times 8}{3}-b$$

Whakareatia te 2 ki te 8, ka 16.

$$4=\frac{16}{3}-b$$

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

$$\frac{16}{3}-b=4$$

Tangohia te \frac{16}{3} mai i ngā taha e rua.

$$-b=4-\frac{16}{3}$$

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

$$-b=\frac{12}{3}-\frac{16}{3}$$

Tā te mea he rite te tauraro o \frac{12}{3} me \frac{16}{3}, me tango rāua mā te tango i ō raua taurunga.

$$-b=\frac{12-16}{3}$$

Tangohia te 16 i te 12, ka -4.

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

Me whakarea ngā taha e rua ki te -1.

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