Kua tāruatia ki te papatopenga
-2y=4-x
Tangohia te x mai i ngā taha e rua.
\frac{-2y}{-2}=\frac{4-x}{-2}
Whakawehea ngā taha e rua ki te -2.
y=\frac{4-x}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=\frac{x}{2}-2
Whakawehe 4-x ki te -2.
x=4+2y
Me tāpiri te 2y ki ngā taha e rua.
