Kua tāruatia ki te papatopenga
-3y=9-x
Tangohia te x mai i ngā taha e rua.
\frac{-3y}{-3}=\frac{9-x}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{9-x}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=\frac{x}{3}-3
Whakawehe 9-x ki te -3.
x=9+3y
Me tāpiri te 3y ki ngā taha e rua.
