Tohaina
Kua tāruatia ki te papatopenga
5x=9-18y
Tangohia te 18y mai i ngā taha e rua.
\frac{5x}{5}=\frac{9-18y}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{9-18y}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
18y=9-5x
Tangohia te 5x mai i ngā taha e rua.
\frac{18y}{18}=\frac{9-5x}{18}
Whakawehea ngā taha e rua ki te 18.
y=\frac{9-5x}{18}
Mā te whakawehe ki te 18 ka wetekia te whakareanga ki te 18.
y=-\frac{5x}{18}+\frac{1}{2}
Whakawehe 9-5x ki te 18.
