Kua tāruatia ki te papatopenga
5x+y=18
Whakareatia te 3 ki te 6, ka 18.
5x=18-y
Tangohia te y mai i ngā taha e rua.
\frac{5x}{5}=\frac{18-y}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{18-y}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
5x+y=18
Whakareatia te 3 ki te 6, ka 18.
y=18-5x
Tangohia te 5x mai i ngā taha e rua.
