Kua tāruatia ki te papatopenga
2x=20-3y
Tangohia te 3y mai i ngā taha e rua.
\frac{2x}{2}=\frac{20-3y}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{20-3y}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=-\frac{3y}{2}+10
Whakawehe 20-3y ki te 2.
3y=20-2x
Tangohia te 2x mai i ngā taha e rua.
\frac{3y}{3}=\frac{20-2x}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{20-2x}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
