Kua tāruatia ki te papatopenga
-\frac{1}{2}x=-5-y
Tangohia te y mai i ngā taha e rua.
-\frac{1}{2}x=-y-5
He hanga arowhānui tō te whārite.
\frac{-\frac{1}{2}x}{-\frac{1}{2}}=\frac{-y-5}{-\frac{1}{2}}
Me whakarea ngā taha e rua ki te -2.
x=\frac{-y-5}{-\frac{1}{2}}
Mā te whakawehe ki te -\frac{1}{2} ka wetekia te whakareanga ki te -\frac{1}{2}.
x=2y+10
Whakawehe -5-y ki te -\frac{1}{2} mā te whakarea -5-y ki te tau huripoki o -\frac{1}{2}.
y=-5+\frac{1}{2}x
Me tāpiri te \frac{1}{2}x ki ngā taha e rua.
