Whakaoti i te 1/4x+1/5=-5

$$\frac { 1 } { 4 } x + \frac { 1 } { 5 } = - 5$$

Whakaoti mō x

$$x = -\frac{104}{5} = -20\frac{4}{5} = -20.8$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te \frac{1}{5} mai i ngā taha e rua.

$$\frac{1}{4}x=-5-\frac{1}{5}$$

Me tahuri te -5 ki te hautau -\frac{25}{5}.

$$\frac{1}{4}x=-\frac{25}{5}-\frac{1}{5}$$

Tā te mea he rite te tauraro o -\frac{25}{5} me \frac{1}{5}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{1}{4}x=\frac{-25-1}{5}$$

Tangohia te 1 i te -25, ka -26.

$$\frac{1}{4}x=-\frac{26}{5}$$

Me whakarea ngā taha e rua ki te 4, te tau utu o \frac{1}{4}.

$$x=-\frac{26}{5}\times 4$$

Tuhia te -\frac{26}{5}\times 4 hei hautanga kotahi.

$$x=\frac{-26\times 4}{5}$$

Whakareatia te -26 ki te 4, ka -104.

$$x=\frac{-104}{5}$$

Ka taea te hautanga \frac{-104}{5} te tuhi anō ko -\frac{104}{5} mā te tango i te tohu tōraro.

$$x=-\frac{104}{5}$$
