Kua tāruatia ki te papatopenga
3x=50-2y
Tangohia te 2y mai i ngā taha e rua.
\frac{3x}{3}=\frac{50-2y}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{50-2y}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
2y=50-3x
Tangohia te 3x mai i ngā taha e rua.
\frac{2y}{2}=\frac{50-3x}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{50-3x}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=-\frac{3x}{2}+25
Whakawehe 50-3x ki te 2.
