Kua tāruatia ki te papatopenga
x\times 7=\left(x+8\right)\times 3
Tē taea kia ōrite te tāupe x ki tētahi o ngā uara -8,0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te x\left(x+8\right), arā, te tauraro pātahi he tino iti rawa te kitea o x+8,x.
x\times 7=3x+24
Whakamahia te āhuatanga tohatoha hei whakarea te x+8 ki te 3.
x\times 7-3x=24
Tangohia te 3x mai i ngā taha e rua.
4x=24
Pahekotia te x\times 7 me -3x, ka 4x.
x=\frac{24}{4}
Whakawehea ngā taha e rua ki te 4.
x=6
Whakawehea te 24 ki te 4, kia riro ko 6.
