Kua tāruatia ki te papatopenga
28+198x=-x
Whakaarohia te whārite tuatahi. Whakareatia te 3 ki te 66, ka 198.
28+198x+x=0
Me tāpiri te x ki ngā taha e rua.
28+199x=0
Pahekotia te 198x me x, ka 199x.
199x=-28
Tangohia te 28 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=-\frac{28}{199}
Whakawehea ngā taha e rua ki te 199.
x=-\frac{28}{199} y=1 z=1 a=1 b=1 c=1 d=1
Kua oti te pūnaha te whakatau.
