Kua tāruatia ki te papatopenga
y-x=3
Whakaarohia te whārite tuatahi. Tangohia te x mai i ngā taha e rua.
10x+y-x=y
Whakaarohia te whārite tuarua. Tangohia te x mai i ngā taha e rua.
9x+y=y
Pahekotia te 10x me -x, ka 9x.
9x+y-y=0
Tangohia te y mai i ngā taha e rua.
9x=0
Pahekotia te y me -y, ka 0.
x=0
Whakawehea ngā taha e rua ki te 9. Ko te kore i whakawehea ki te tau ehara te kore ka hua ko te kore.
y-0=3
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
y+0=3
Whakareatia te -1 ki te 0, ka 0.
y=3
Ko te tau i tāpiria he kore ka hua koia tonu.
y=3 x=0
Kua oti te pūnaha te whakatau.
