4000000000\left(0\times 2-\frac{x}{200000}\right)=3200000000\left(0\times 3-\frac{x}{80000}\right)
Me whakarea ngā taha e rua o te whārite ki te 400000, arā, te tauraro pātahi he tino iti rawa te kitea o 200000,80000.
4000000000\left(0-\frac{x}{200000}\right)=3200000000\left(0\times 3-\frac{x}{80000}\right)
Whakareatia te 0 ki te 2, ka 0.
4000000000\left(-\frac{x}{200000}\right)=3200000000\left(0\times 3-\frac{x}{80000}\right)
Ko te tau i tāpiria he kore ka hua koia tonu.
-20000x=3200000000\left(0\times 3-\frac{x}{80000}\right)
Whakakorea atu te tauwehe pūnoa nui rawa 200000 i roto i te 4000000000 me te 200000.
-20000x=3200000000\left(0-\frac{x}{80000}\right)
Whakareatia te 0 ki te 3, ka 0.
-20000x=3200000000\left(-\frac{x}{80000}\right)
Ko te tau i tāpiria he kore ka hua koia tonu.
-20000x=-40000x
Whakakorea atu te tauwehe pūnoa nui rawa 80000 i roto i te 3200000000 me te 80000.
-20000x+40000x=0
Me tāpiri te 40000x ki ngā taha e rua.
20000x=0
Pahekotia te -20000x me 40000x, ka 20000x.
x=0
He ōrite te hua o ngā tau e rua ki 0 ina 0 tētahi o rāua te iti rawa. Tātemea kāore te 20000 e ōrite ki 0, me ōrite pū te x ki 0.
