Whakaoti mō x
x=\frac{z}{7}
Whakaoti mō z
z=7x
Tohaina
Kua tāruatia ki te papatopenga
z=7x
Pahekotia te 3x me 4x, ka 7x.
7x=z
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{7x}{7}=\frac{z}{7}
Whakawehea ngā taha e rua ki te 7.
x=\frac{z}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
z=7x
Pahekotia te 3x me 4x, ka 7x.
