Tohaina
Kua tāruatia ki te papatopenga
-x=20-y
Tangohia te y mai i ngā taha e rua.
\frac{-x}{-1}=\frac{20-y}{-1}
Whakawehea ngā taha e rua ki te -1.
x=\frac{20-y}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
x=y-20
Whakawehe 20-y ki te -1.
y=20+x
Me tāpiri te x ki ngā taha e rua.
