Kua tāruatia ki te papatopenga
5x=18+8y
Me tāpiri te 8y ki ngā taha e rua.
5x=8y+18
He hanga arowhānui tō te whārite.
\frac{5x}{5}=\frac{8y+18}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{8y+18}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
-8y=18-5x
Tangohia te 5x mai i ngā taha e rua.
\frac{-8y}{-8}=\frac{18-5x}{-8}
Whakawehea ngā taha e rua ki te -8.
y=\frac{18-5x}{-8}
Mā te whakawehe ki te -8 ka wetekia te whakareanga ki te -8.
y=\frac{5x}{8}-\frac{9}{4}
Whakawehe 18-5x ki te -8.
