Kua tāruatia ki te papatopenga
2x=16+5y
Me tāpiri te 5y ki ngā taha e rua.
2x=5y+16
He hanga arowhānui tō te whārite.
\frac{2x}{2}=\frac{5y+16}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{5y+16}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=\frac{5y}{2}+8
Whakawehe 16+5y ki te 2.
-5y=16-2x
Tangohia te 2x mai i ngā taha e rua.
\frac{-5y}{-5}=\frac{16-2x}{-5}
Whakawehea ngā taha e rua ki te -5.
y=\frac{16-2x}{-5}
Mā te whakawehe ki te -5 ka wetekia te whakareanga ki te -5.
y=\frac{2x-16}{5}
Whakawehe 16-2x ki te -5.
