Kua tāruatia ki te papatopenga
2x=11-y
Tangohia te 1y mai i ngā taha e rua.
\frac{2x}{2}=\frac{11-y}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{11-y}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
1y=11-2x
Tangohia te 2x mai i ngā taha e rua.
y=-2x+11
Whakaraupapatia anō ngā kīanga tau.
