Kua tāruatia ki te papatopenga
-5x=13+2y
Me tāpiri te 2y ki ngā taha e rua.
-5x=2y+13
He hanga arowhānui tō te whārite.
\frac{-5x}{-5}=\frac{2y+13}{-5}
Whakawehea ngā taha e rua ki te -5.
x=\frac{2y+13}{-5}
Mā te whakawehe ki te -5 ka wetekia te whakareanga ki te -5.
x=\frac{-2y-13}{5}
Whakawehe 13+2y ki te -5.
-2y=13+5x
Me tāpiri te 5x ki ngā taha e rua.
-2y=5x+13
He hanga arowhānui tō te whārite.
\frac{-2y}{-2}=\frac{5x+13}{-2}
Whakawehea ngā taha e rua ki te -2.
y=\frac{5x+13}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=\frac{-5x-13}{2}
Whakawehe 13+5x ki te -2.
