Tohaina
Kua tāruatia ki te papatopenga
rz=125+125z
Whakareatia ngā taha e rua o te whārite ki te 25.
zr=125z+125
He hanga arowhānui tō te whārite.
\frac{zr}{z}=\frac{125z+125}{z}
Whakawehea ngā taha e rua ki te z.
r=\frac{125z+125}{z}
Mā te whakawehe ki te z ka wetekia te whakareanga ki te z.
r=125+\frac{125}{z}
Whakawehe 125+125z ki te z.
rz=125+125z
Whakareatia ngā taha e rua o te whārite ki te 25.
rz-125z=125
Tangohia te 125z mai i ngā taha e rua.
\left(r-125\right)z=125
Pahekotia ngā kīanga tau katoa e whai ana i te z.
\frac{\left(r-125\right)z}{r-125}=\frac{125}{r-125}
Whakawehea ngā taha e rua ki te r-125.
z=\frac{125}{r-125}
Mā te whakawehe ki te r-125 ka wetekia te whakareanga ki te r-125.
