Kua tāruatia ki te papatopenga
2+2x\times 5=1
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 2x, arā, te tauraro pātahi he tino iti rawa te kitea o x,2x.
2+10x=1
Whakareatia te 2 ki te 5, ka 10.
10x=1-2
Tangohia te 2 mai i ngā taha e rua.
10x=-1
Tangohia te 2 i te 1, ka -1.
x=\frac{-1}{10}
Whakawehea ngā taha e rua ki te 10.
x=-\frac{1}{10}
Ka taea te hautanga \frac{-1}{10} te tuhi anō ko -\frac{1}{10} mā te tango i te tohu tōraro.
