Kua tāruatia ki te papatopenga
7x=14-y
Tangohia te y mai i ngā taha e rua.
\frac{7x}{7}=\frac{14-y}{7}
Whakawehea ngā taha e rua ki te 7.
x=\frac{14-y}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
x=-\frac{y}{7}+2
Whakawehe 14-y ki te 7.
y=14-7x
Tangohia te 7x mai i ngā taha e rua.
