Whakaoti i te 1=a(25/4)+3

$$1 = a ( \frac { 25 } { 4 } ) + 3$$

Whakaoti mō a

$$a=-\frac{8}{25}=-0.32$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$a\times \frac{25}{4}+3=1$$

Tangohia te 3 mai i ngā taha e rua.

$$a\times \frac{25}{4}=1-3$$

Tangohia te 3 i te 1, ka -2.

$$a\times \frac{25}{4}=-2$$

Me whakarea ngā taha e rua ki te \frac{4}{25}, te tau utu o \frac{25}{4}.

$$a=-2\times \frac{4}{25}$$

Tuhia te -2\times \frac{4}{25} hei hautanga kotahi.

$$a=\frac{-2\times 4}{25}$$

Whakareatia te -2 ki te 4, ka -8.

$$a=\frac{-8}{25}$$

Ka taea te hautanga \frac{-8}{25} te tuhi anō ko -\frac{8}{25} mā te tango i te tohu tōraro.

$$a=-\frac{8}{25}$$
