Kua tāruatia ki te papatopenga
5\left(x+5\right)=2\times 3x
Tē taea kia ōrite te tāupe x ki -5 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 2\left(x+5\right), arā, te tauraro pātahi he tino iti rawa te kitea o 2,x+5.
5x+25=2\times 3x
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x+5.
5x+25=6x
Whakareatia te 2 ki te 3, ka 6.
5x+25-6x=0
Tangohia te 6x mai i ngā taha e rua.
-x+25=0
Pahekotia te 5x me -6x, ka -x.
-x=-25
Tangohia te 25 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=25
Me whakarea ngā taha e rua ki te -1.
