-2x=-10-5y
Tangohia te 5y mai i ngā taha e rua.
-2x=-5y-10
He hanga arowhānui tō te whārite.
\frac{-2x}{-2}=\frac{-5y-10}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{-5y-10}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=\frac{5y}{2}+5
Whakawehe -10-5y ki te -2.
5y=-10+2x
Me tāpiri te 2x ki ngā taha e rua.
5y=2x-10
He hanga arowhānui tō te whārite.
\frac{5y}{5}=\frac{2x-10}{5}
Whakawehea ngā taha e rua ki te 5.
y=\frac{2x-10}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
y=\frac{2x}{5}-2
Whakawehe -10+2x ki te 5.
