Kua tāruatia ki te papatopenga
w+6=2w-12
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te w-6.
w+6-2w=-12
Tangohia te 2w mai i ngā taha e rua.
-w+6=-12
Pahekotia te w me -2w, ka -w.
-w=-12-6
Tangohia te 6 mai i ngā taha e rua.
-w=-18
Tangohia te 6 i te -12, ka -18.
w=18
Me whakarea ngā taha e rua ki te -1.
