Kua tāruatia ki te papatopenga
x\times 340=\left(x+10\right)\times 290
Tē taea kia ōrite te tāupe x ki tētahi o ngā uara -10,0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te x\left(x+10\right), arā, te tauraro pātahi he tino iti rawa te kitea o x+10,x.
x\times 340=290x+2900
Whakamahia te āhuatanga tohatoha hei whakarea te x+10 ki te 290.
x\times 340-290x=2900
Tangohia te 290x mai i ngā taha e rua.
50x=2900
Pahekotia te x\times 340 me -290x, ka 50x.
x=\frac{2900}{50}
Whakawehea ngā taha e rua ki te 50.
x=58
Whakawehea te 2900 ki te 50, kia riro ko 58.
