Whakaoti i te 3(3a-2)=4(4-a)

$$3 ( 3 a - 2 ) = 4 ( 4 - a )$$

Whakaoti mō a

$$a = \frac{22}{13} = 1\frac{9}{13} \approx 1.692307692$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 3a-2.

$$9a-6=4\left(4-a\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 4-a.

$$9a-6=16-4a$$

Me tāpiri te 4a ki ngā taha e rua.

$$9a-6+4a=16$$

Pahekotia te 9a me 4a, ka 13a.

$$13a-6=16$$

Me tāpiri te 6 ki ngā taha e rua.

$$13a=16+6$$

Tāpirihia te 16 ki te 6, ka 22.

$$13a=22$$

Whakawehea ngā taha e rua ki te 13.

$$a=\frac{22}{13}$$
