Kua tāruatia ki te papatopenga
-x-480=-x_{2}
Tangohia te x_{2} mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-x=-x_{2}+480
Me tāpiri te 480 ki ngā taha e rua.
-x=480-x_{2}
He hanga arowhānui tō te whārite.
\frac{-x}{-1}=\frac{480-x_{2}}{-1}
Whakawehea ngā taha e rua ki te -1.
x=\frac{480-x_{2}}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
x=x_{2}-480
Whakawehe -x_{2}+480 ki te -1.
x_{2}-480=x
Me tāpiri te x ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x_{2}=x+480
Me tāpiri te 480 ki ngā taha e rua.
