Kua tāruatia ki te papatopenga
8x=32-7y
Tangohia te 7y mai i ngā taha e rua.
\frac{8x}{8}=\frac{32-7y}{8}
Whakawehea ngā taha e rua ki te 8.
x=\frac{32-7y}{8}
Mā te whakawehe ki te 8 ka wetekia te whakareanga ki te 8.
x=-\frac{7y}{8}+4
Whakawehe 32-7y ki te 8.
7y=32-8x
Tangohia te 8x mai i ngā taha e rua.
\frac{7y}{7}=\frac{32-8x}{7}
Whakawehea ngā taha e rua ki te 7.
y=\frac{32-8x}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
