Kua tāruatia ki te papatopenga
7x=7-3y
Tangohia te 3y mai i ngā taha e rua.
\frac{7x}{7}=\frac{7-3y}{7}
Whakawehea ngā taha e rua ki te 7.
x=\frac{7-3y}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
x=-\frac{3y}{7}+1
Whakawehe 7-3y ki te 7.
3y=7-7x
Tangohia te 7x mai i ngā taha e rua.
\frac{3y}{3}=\frac{7-7x}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{7-7x}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
