Kua tāruatia ki te papatopenga
6x-80=x+40
Whakareatia ngā taha e rua o te whārite ki te 2.
6x-80-x=40
Tangohia te x mai i ngā taha e rua.
5x-80=40
Pahekotia te 6x me -x, ka 5x.
5x=40+80
Me tāpiri te 80 ki ngā taha e rua.
5x=120
Tāpirihia te 40 ki te 80, ka 120.
x=\frac{120}{5}
Whakawehea ngā taha e rua ki te 5.
x=24
Whakawehea te 120 ki te 5, kia riro ko 24.
