Tohaina
Kua tāruatia ki te papatopenga
400x=579-20y
Tangohia te 20y mai i ngā taha e rua.
\frac{400x}{400}=\frac{579-20y}{400}
Whakawehea ngā taha e rua ki te 400.
x=\frac{579-20y}{400}
Mā te whakawehe ki te 400 ka wetekia te whakareanga ki te 400.
x=-\frac{y}{20}+\frac{579}{400}
Whakawehe 579-20y ki te 400.
20y=579-400x
Tangohia te 400x mai i ngā taha e rua.
\frac{20y}{20}=\frac{579-400x}{20}
Whakawehea ngā taha e rua ki te 20.
y=\frac{579-400x}{20}
Mā te whakawehe ki te 20 ka wetekia te whakareanga ki te 20.
y=\frac{579}{20}-20x
Whakawehe 579-400x ki te 20.
