\frac{10485-x}{x}=\frac{825}{100}
Whakawehea ngā taha e rua ki te 100.
\frac{10485-x}{x}=\frac{33}{4}
Whakahekea te hautanga \frac{825}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.
4\left(10485-x\right)=33x
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 4x, arā, te tauraro pātahi he tino iti rawa te kitea o x,4.
41940-4x=33x
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 10485-x.
41940-4x-33x=0
Tangohia te 33x mai i ngā taha e rua.
41940-37x=0
Pahekotia te -4x me -33x, ka -37x.
-37x=-41940
Tangohia te 41940 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-41940}{-37}
Whakawehea ngā taha e rua ki te -37.
x=\frac{41940}{37}
Ka taea te hautanga \frac{-41940}{-37} te whakamāmā ki te \frac{41940}{37} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
