Kua tāruatia ki te papatopenga
\left(1-0\right)x=208x
Whakareatia te 0 ki te 15, ka 0.
1x=208x
Tangohia te 0 i te 1, ka 1.
1x-208x=0
Tangohia te 208x mai i ngā taha e rua.
-207x=0
Pahekotia te 1x me -208x, ka -207x.
x=0
He ōrite te hua o ngā tau e rua ki 0 ina 0 tētahi o rāua te iti rawa. Tātemea kāore te -207 e ōrite ki 0, me ōrite pū te x ki 0.
