Kua tāruatia ki te papatopenga
30x=700-y
Tangohia te y mai i ngā taha e rua.
\frac{30x}{30}=\frac{700-y}{30}
Whakawehea ngā taha e rua ki te 30.
x=\frac{700-y}{30}
Mā te whakawehe ki te 30 ka wetekia te whakareanga ki te 30.
x=-\frac{y}{30}+\frac{70}{3}
Whakawehe 700-y ki te 30.
y=700-30x
Tangohia te 30x mai i ngā taha e rua.
