Tohaina
Kua tāruatia ki te papatopenga
xy=4-B
Tangohia te B mai i ngā taha e rua.
yx=4-B
He hanga arowhānui tō te whārite.
\frac{yx}{y}=\frac{4-B}{y}
Whakawehea ngā taha e rua ki te y.
x=\frac{4-B}{y}
Mā te whakawehe ki te y ka wetekia te whakareanga ki te y.
xy=4-B
Tangohia te B mai i ngā taha e rua.
yx=4-B
He hanga arowhānui tō te whārite.
\frac{yx}{y}=\frac{4-B}{y}
Whakawehea ngā taha e rua ki te y.
x=\frac{4-B}{y}
Mā te whakawehe ki te y ka wetekia te whakareanga ki te y.
B=4-xy
Tangohia te xy mai i ngā taha e rua.
