Kua tāruatia ki te papatopenga
x-11=2y
Me tāpiri te 2y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=2y+11
Me tāpiri te 11 ki ngā taha e rua.
-2y-11=-x
Tangohia te x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-2y=-x+11
Me tāpiri te 11 ki ngā taha e rua.
-2y=11-x
He hanga arowhānui tō te whārite.
\frac{-2y}{-2}=\frac{11-x}{-2}
Whakawehea ngā taha e rua ki te -2.
y=\frac{11-x}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=\frac{x-11}{2}
Whakawehe -x+11 ki te -2.
