Tohaina
Kua tāruatia ki te papatopenga
\left(5s+4\right)\times 2=\left(s-3\right)\times 9
Tē taea kia ōrite te tāupe s ki tētahi o ngā uara -\frac{4}{5},3 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te \left(s-3\right)\left(5s+4\right), arā, te tauraro pātahi he tino iti rawa te kitea o s-3,5s+4.
10s+8=\left(s-3\right)\times 9
Whakamahia te āhuatanga tohatoha hei whakarea te 5s+4 ki te 2.
10s+8=9s-27
Whakamahia te āhuatanga tohatoha hei whakarea te s-3 ki te 9.
10s+8-9s=-27
Tangohia te 9s mai i ngā taha e rua.
s+8=-27
Pahekotia te 10s me -9s, ka s.
s=-27-8
Tangohia te 8 mai i ngā taha e rua.
s=-35
Tangohia te 8 i te -27, ka -35.
