0-2\left(48x+0\times 63\right)=0\times 7x
Whakareatia te 0 ki te 88, ka 0.
0-2\times 48x=0\times 7x
Whakareatia te 0 ki te 63, ka 0.
0-96x=0\times 7x
Whakareatia te -2 ki te 48, ka -96.
-96x=0\times 7x
Ko te tau i tāpiria he kore ka hua koia tonu.
-96x=0x
Whakareatia te 0 ki te 7, ka 0.
-96x=0
Ko te tau i whakarea ki te kore ka hua ko te kore.
x=0
He ōrite te hua o ngā tau e rua ki 0 ina 0 tētahi o rāua te iti rawa. Tātemea kāore te -96 e ōrite ki 0, me ōrite pū te x ki 0.
