Kua tāruatia ki te papatopenga
5x=-43+9y
Me tāpiri te 9y ki ngā taha e rua.
5x=9y-43
He hanga arowhānui tō te whārite.
\frac{5x}{5}=\frac{9y-43}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{9y-43}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
-9y=-43-5x
Tangohia te 5x mai i ngā taha e rua.
-9y=-5x-43
He hanga arowhānui tō te whārite.
\frac{-9y}{-9}=\frac{-5x-43}{-9}
Whakawehea ngā taha e rua ki te -9.
y=\frac{-5x-43}{-9}
Mā te whakawehe ki te -9 ka wetekia te whakareanga ki te -9.
y=\frac{5x+43}{9}
Whakawehe -43-5x ki te -9.
