Whakaoti i te 1/3x+1/4=-2

$$\frac { 1 } { 3 } x + \frac { 1 } { 4 } = - 2$$

Whakaoti mō x

$$x = -\frac{27}{4} = -6\frac{3}{4} = -6.75$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te \frac{1}{4} mai i ngā taha e rua.

$$\frac{1}{3}x=-2-\frac{1}{4}$$

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

$$\frac{1}{3}x=-\frac{8}{4}-\frac{1}{4}$$

Tā te mea he rite te tauraro o -\frac{8}{4} me \frac{1}{4}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{1}{3}x=\frac{-8-1}{4}$$

Tangohia te 1 i te -8, ka -9.

$$\frac{1}{3}x=-\frac{9}{4}$$

Me whakarea ngā taha e rua ki te 3, te tau utu o \frac{1}{3}.

$$x=-\frac{9}{4}\times 3$$

Tuhia te -\frac{9}{4}\times 3 hei hautanga kotahi.

$$x=\frac{-9\times 3}{4}$$

Whakareatia te -9 ki te 3, ka -27.

$$x=\frac{-27}{4}$$

Ka taea te hautanga \frac{-27}{4} te tuhi anō ko -\frac{27}{4} mā te tango i te tohu tōraro.

$$x=-\frac{27}{4}$$
