Kua tāruatia ki te papatopenga
ex=15+y
Me tāpiri te y ki ngā taha e rua.
ex=y+15
He hanga arowhānui tō te whārite.
\frac{ex}{e}=\frac{y+15}{e}
Whakawehea ngā taha e rua ki te e.
x=\frac{y+15}{e}
Mā te whakawehe ki te e ka wetekia te whakareanga ki te e.
-y=15-ex
Tangohia te ex mai i ngā taha e rua.
\frac{-y}{-1}=\frac{15-ex}{-1}
Whakawehea ngā taha e rua ki te -1.
y=\frac{15-ex}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
y=ex-15
Whakawehe -ex+15 ki te -1.
