Kua tāruatia ki te papatopenga
x+10=y
Me tāpiri te y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=y-10
Tangohia te 10 mai i ngā taha e rua.
-y+10=-x
Tangohia te x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-y=-x-10
Tangohia te 10 mai i ngā taha e rua.
\frac{-y}{-1}=\frac{-x-10}{-1}
Whakawehea ngā taha e rua ki te -1.
y=\frac{-x-10}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
y=x+10
Whakawehe -x-10 ki te -1.
