Kua tāruatia ki te papatopenga
9y=15-x
Tangohia te x mai i ngā taha e rua.
\frac{9y}{9}=\frac{15-x}{9}
Whakawehea ngā taha e rua ki te 9.
y=\frac{15-x}{9}
Mā te whakawehe ki te 9 ka wetekia te whakareanga ki te 9.
y=-\frac{x}{9}+\frac{5}{3}
Whakawehe 15-x ki te 9.
x=15-9y
Tangohia te 9y mai i ngā taha e rua.
