Kua tāruatia ki te papatopenga
6\left(x+1\right)-5\left(x-3\right)=0
Me whakarea ngā taha e rua o te whārite ki te 30, arā, te tauraro pātahi he tino iti rawa te kitea o 5,6.
6x+6-5\left(x-3\right)=0
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te x+1.
6x+6-5x+15=0
Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te x-3.
x+6+15=0
Pahekotia te 6x me -5x, ka x.
x+21=0
Tāpirihia te 6 ki te 15, ka 21.
x=-21
Tangohia te 21 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
