Whakaoti i te 2x+2=3/4

$$2x+2= \frac{ 3 }{ 4 }$$

Whakaoti mō x

$$x=-\frac{5}{8}=-0.625$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te 2 mai i ngā taha e rua.

$$2x=\frac{3}{4}-2$$

Me tahuri te 2 ki te hautau \frac{8}{4}.

$$2x=\frac{3}{4}-\frac{8}{4}$$

Tā te mea he rite te tauraro o \frac{3}{4} me \frac{8}{4}, me tango rāua mā te tango i ō raua taurunga.

$$2x=\frac{3-8}{4}$$

Tangohia te 8 i te 3, ka -5.

$$2x=-\frac{5}{4}$$

Whakawehea ngā taha e rua ki te 2.

$$x=\frac{-\frac{5}{4}}{2}$$

Tuhia te \frac{-\frac{5}{4}}{2} hei hautanga kotahi.

$$x=\frac{-5}{4\times 2}$$

Whakareatia te 4 ki te 2, ka 8.

$$x=\frac{-5}{8}$$

Ka taea te hautanga \frac{-5}{8} te tuhi anō ko -\frac{5}{8} mā te tango i te tohu tōraro.

$$x=-\frac{5}{8}$$
