Kua tāruatia ki te papatopenga
x\times 312=\left(x+27\right)\times 150
Tē taea kia ōrite te tāupe x ki tētahi o ngā uara -27,0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te x\left(x+27\right), arā, te tauraro pātahi he tino iti rawa te kitea o x+27,x.
x\times 312=150x+4050
Whakamahia te āhuatanga tohatoha hei whakarea te x+27 ki te 150.
x\times 312-150x=4050
Tangohia te 150x mai i ngā taha e rua.
162x=4050
Pahekotia te x\times 312 me -150x, ka 162x.
x=\frac{4050}{162}
Whakawehea ngā taha e rua ki te 162.
x=25
Whakawehea te 4050 ki te 162, kia riro ko 25.
