Kua tāruatia ki te papatopenga
2x=-2+5y
Me tāpiri te 5y ki ngā taha e rua.
2x=5y-2
He hanga arowhānui tō te whārite.
\frac{2x}{2}=\frac{5y-2}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{5y-2}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=\frac{5y}{2}-1
Whakawehe -2+5y ki te 2.
-5y=-2-2x
Tangohia te 2x mai i ngā taha e rua.
-5y=-2x-2
He hanga arowhānui tō te whārite.
\frac{-5y}{-5}=\frac{-2x-2}{-5}
Whakawehea ngā taha e rua ki te -5.
y=\frac{-2x-2}{-5}
Mā te whakawehe ki te -5 ka wetekia te whakareanga ki te -5.
y=\frac{2x+2}{5}
Whakawehe -2-2x ki te -5.
