Kua tāruatia ki te papatopenga
-3y=-5-x
Tangohia te x mai i ngā taha e rua.
-3y=-x-5
He hanga arowhānui tō te whārite.
\frac{-3y}{-3}=\frac{-x-5}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{-x-5}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=\frac{x+5}{3}
Whakawehe -5-x ki te -3.
x=-5+3y
Me tāpiri te 3y ki ngā taha e rua.
