Kua tāruatia ki te papatopenga
5\left(2x-1\right)\times \frac{3}{5}+5\times 3=0
Tē taea kia ōrite te tāupe x ki \frac{1}{2} nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 5\left(2x-1\right), arā, te tauraro pātahi he tino iti rawa te kitea o 5,2x-1.
\left(10x-5\right)\times \frac{3}{5}+5\times 3=0
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 2x-1.
6x-3+5\times 3=0
Whakamahia te āhuatanga tohatoha hei whakarea te 10x-5 ki te \frac{3}{5}.
6x-3+15=0
Whakareatia te 5 ki te 3, ka 15.
6x+12=0
Tāpirihia te -3 ki te 15, ka 12.
6x=-12
Tangohia te 12 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-12}{6}
Whakawehea ngā taha e rua ki te 6.
x=-2
Whakawehea te -12 ki te 6, kia riro ko -2.
