Kua tāruatia ki te papatopenga
3\left(3x+500\right)=25\left(x-100\right)
Tē taea kia ōrite te tāupe x ki 100 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 15\left(x-100\right), arā, te tauraro pātahi he tino iti rawa te kitea o 5x-500,3.
9x+1500=25\left(x-100\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 3x+500.
9x+1500=25x-2500
Whakamahia te āhuatanga tohatoha hei whakarea te 25 ki te x-100.
9x+1500-25x=-2500
Tangohia te 25x mai i ngā taha e rua.
-16x+1500=-2500
Pahekotia te 9x me -25x, ka -16x.
-16x=-2500-1500
Tangohia te 1500 mai i ngā taha e rua.
-16x=-4000
Tangohia te 1500 i te -2500, ka -4000.
x=\frac{-4000}{-16}
Whakawehea ngā taha e rua ki te -16.
x=250
Whakawehea te -4000 ki te -16, kia riro ko 250.
