Kua tāruatia ki te papatopenga
\left(x+100\right)\times 22=x\times 33
Tē taea kia ōrite te tāupe x ki tētahi o ngā uara -100,0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te x\left(x+100\right), arā, te tauraro pātahi he tino iti rawa te kitea o x,x+100.
22x+2200=x\times 33
Whakamahia te āhuatanga tohatoha hei whakarea te x+100 ki te 22.
22x+2200-x\times 33=0
Tangohia te x\times 33 mai i ngā taha e rua.
-11x+2200=0
Pahekotia te 22x me -x\times 33, ka -11x.
-11x=-2200
Tangohia te 2200 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-2200}{-11}
Whakawehea ngā taha e rua ki te -11.
x=200
Whakawehea te -2200 ki te -11, kia riro ko 200.
