Kua tāruatia ki te papatopenga
-x+7y=-8
Pahekotia te x me -2x, ka -x.
-x=-8-7y
Tangohia te 7y mai i ngā taha e rua.
-x=-7y-8
He hanga arowhānui tō te whārite.
\frac{-x}{-1}=\frac{-7y-8}{-1}
Whakawehea ngā taha e rua ki te -1.
x=\frac{-7y-8}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
x=7y+8
Whakawehe -8-7y ki te -1.
