Kua tāruatia ki te papatopenga
x+10=3y
Me tāpiri te 3y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=3y-10
Tangohia te 10 mai i ngā taha e rua.
-3y+10=-x
Tangohia te x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-3y=-x-10
Tangohia te 10 mai i ngā taha e rua.
\frac{-3y}{-3}=\frac{-x-10}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{-x-10}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=\frac{x+10}{3}
Whakawehe -x-10 ki te -3.
