Whakaoti i te 7+3x=16:3

$$7 + 3 x = 16 : 3$$

Whakaoti mō x

$$x=-\frac{5}{9}\approx -0.555555556$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te 7 mai i ngā taha e rua.

$$3x=\frac{16}{3}-7$$

Me tahuri te 7 ki te hautau \frac{21}{3}.

$$3x=\frac{16}{3}-\frac{21}{3}$$

Tā te mea he rite te tauraro o \frac{16}{3} me \frac{21}{3}, me tango rāua mā te tango i ō raua taurunga.

$$3x=\frac{16-21}{3}$$

Tangohia te 21 i te 16, ka -5.

$$3x=-\frac{5}{3}$$

Whakawehea ngā taha e rua ki te 3.

$$x=\frac{-\frac{5}{3}}{3}$$

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

$$x=\frac{-5}{3\times 3}$$

Whakareatia te 3 ki te 3, ka 9.

$$x=\frac{-5}{9}$$

Ka taea te hautanga \frac{-5}{9} te tuhi anō ko -\frac{5}{9} mā te tango i te tohu tōraro.

$$x=-\frac{5}{9}$$
