Kua tāruatia ki te papatopenga
2000x=10+1000y
Me tāpiri te 1000y ki ngā taha e rua.
2000x=1000y+10
He hanga arowhānui tō te whārite.
\frac{2000x}{2000}=\frac{1000y+10}{2000}
Whakawehea ngā taha e rua ki te 2000.
x=\frac{1000y+10}{2000}
Mā te whakawehe ki te 2000 ka wetekia te whakareanga ki te 2000.
x=\frac{y}{2}+\frac{1}{200}
Whakawehe 10+1000y ki te 2000.
-1000y=10-2000x
Tangohia te 2000x mai i ngā taha e rua.
\frac{-1000y}{-1000}=\frac{10-2000x}{-1000}
Whakawehea ngā taha e rua ki te -1000.
y=\frac{10-2000x}{-1000}
Mā te whakawehe ki te -1000 ka wetekia te whakareanga ki te -1000.
y=2x-\frac{1}{100}
Whakawehe 10-2000x ki te -1000.
