Kua tāruatia ki te papatopenga
-2x=1-y
Tangohia te y mai i ngā taha e rua.
\frac{-2x}{-2}=\frac{1-y}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{1-y}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=\frac{y-1}{2}
Whakawehe 1-y ki te -2.
y=1+2x
Me tāpiri te 2x ki ngā taha e rua.
