Kua tāruatia ki te papatopenga
-5x=-8+2y
Me tāpiri te 2y ki ngā taha e rua.
-5x=2y-8
He hanga arowhānui tō te whārite.
\frac{-5x}{-5}=\frac{2y-8}{-5}
Whakawehea ngā taha e rua ki te -5.
x=\frac{2y-8}{-5}
Mā te whakawehe ki te -5 ka wetekia te whakareanga ki te -5.
x=\frac{8-2y}{5}
Whakawehe -8+2y ki te -5.
-2y=-8+5x
Me tāpiri te 5x ki ngā taha e rua.
-2y=5x-8
He hanga arowhānui tō te whārite.
\frac{-2y}{-2}=\frac{5x-8}{-2}
Whakawehea ngā taha e rua ki te -2.
y=\frac{5x-8}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=-\frac{5x}{2}+4
Whakawehe -8+5x ki te -2.
