Kua tāruatia ki te papatopenga
16\left(x+45\right)=x\times 2
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 16x, arā, te tauraro pātahi he tino iti rawa te kitea o x,16.
16x+720=x\times 2
Whakamahia te āhuatanga tohatoha hei whakarea te 16 ki te x+45.
16x+720-x\times 2=0
Tangohia te x\times 2 mai i ngā taha e rua.
14x+720=0
Pahekotia te 16x me -x\times 2, ka 14x.
14x=-720
Tangohia te 720 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-720}{14}
Whakawehea ngā taha e rua ki te 14.
x=-\frac{360}{7}
Whakahekea te hautanga \frac{-720}{14} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
