Kua tāruatia ki te papatopenga
6a+12a\times 7=4x
Whakareatia ngā taha e rua o te whārite ki te 2.
6a+84a=4x
Whakareatia te 12 ki te 7, ka 84.
90a=4x
Pahekotia te 6a me 84a, ka 90a.
\frac{90a}{90}=\frac{4x}{90}
Whakawehea ngā taha e rua ki te 90.
a=\frac{4x}{90}
Mā te whakawehe ki te 90 ka wetekia te whakareanga ki te 90.
a=\frac{2x}{45}
Whakawehe 4x ki te 90.
6a+12a\times 7=4x
Whakareatia ngā taha e rua o te whārite ki te 2.
6a+84a=4x
Whakareatia te 12 ki te 7, ka 84.
90a=4x
Pahekotia te 6a me 84a, ka 90a.
4x=90a
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{4x}{4}=\frac{90a}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{90a}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x=\frac{45a}{2}
Whakawehe 90a ki te 4.
