Kua tāruatia ki te papatopenga
8\left(x+450\right)=9000+2x
Tē taea kia ōrite te tāupe x ki -450 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x+450.
8x+3600=9000+2x
Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te x+450.
8x+3600-2x=9000
Tangohia te 2x mai i ngā taha e rua.
6x+3600=9000
Pahekotia te 8x me -2x, ka 6x.
6x=9000-3600
Tangohia te 3600 mai i ngā taha e rua.
6x=5400
Tangohia te 3600 i te 9000, ka 5400.
x=\frac{5400}{6}
Whakawehea ngā taha e rua ki te 6.
x=900
Whakawehea te 5400 ki te 6, kia riro ko 900.
