Kua tāruatia ki te papatopenga
x+1=2y
Me tāpiri te 2y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=2y-1
Tangohia te 1 mai i ngā taha e rua.
-2y+1=-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-1
Tangohia te 1 mai i ngā taha e rua.
\frac{-2y}{-2}=\frac{-x-1}{-2}
Whakawehea ngā taha e rua ki te -2.
y=\frac{-x-1}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=\frac{x+1}{2}
Whakawehe -x-1 ki te -2.
