Kua tāruatia ki te papatopenga
32\left(25+x\right)=x\times 58
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 32x, arā, te tauraro pātahi he tino iti rawa te kitea o x,32.
800+32x=x\times 58
Whakamahia te āhuatanga tohatoha hei whakarea te 32 ki te 25+x.
800+32x-x\times 58=0
Tangohia te x\times 58 mai i ngā taha e rua.
800-26x=0
Pahekotia te 32x me -x\times 58, ka -26x.
-26x=-800
Tangohia te 800 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-800}{-26}
Whakawehea ngā taha e rua ki te -26.
x=\frac{400}{13}
Whakahekea te hautanga \frac{-800}{-26} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -2.
