Kua tāruatia ki te papatopenga
40\times 133+v=-2v\left(133-1\right)
Tē taea kia ōrite te tāupe v ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 40v, arā, te tauraro pātahi he tino iti rawa te kitea o v,-40,-20.
5320+v=-2v\left(133-1\right)
Whakareatia te 40 ki te 133, ka 5320.
5320+v=-2v\times 132
Tangohia te 1 i te 133, ka 132.
5320+v=-264v
Whakareatia te -2 ki te 132, ka -264.
5320+v+264v=0
Me tāpiri te 264v ki ngā taha e rua.
5320+265v=0
Pahekotia te v me 264v, ka 265v.
265v=-5320
Tangohia te 5320 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
v=\frac{-5320}{265}
Whakawehea ngā taha e rua ki te 265.
v=-\frac{1064}{53}
Whakahekea te hautanga \frac{-5320}{265} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
