Tohaina
Kua tāruatia ki te papatopenga
A=3x-9-x
Hei kimi i te tauaro o 9+x, kimihia te tauaro o ia taurangi.
A=2x-9
Pahekotia te 3x me -x, ka 2x.
A=3x-9-x
Hei kimi i te tauaro o 9+x, kimihia te tauaro o ia taurangi.
A=2x-9
Pahekotia te 3x me -x, ka 2x.
2x-9=A
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2x=A+9
Me tāpiri te 9 ki ngā taha e rua.
\frac{2x}{2}=\frac{A+9}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{A+9}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
