Kua tāruatia ki te papatopenga
2x-3\left(2x+1\right)=x-6x
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 3,2,6.
2x-6x-3=x-6x
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te 2x+1.
-4x-3=x-6x
Pahekotia te 2x me -6x, ka -4x.
-4x-3=-5x
Pahekotia te x me -6x, ka -5x.
-4x-3+5x=0
Me tāpiri te 5x ki ngā taha e rua.
x-3=0
Pahekotia te -4x me 5x, ka x.
x=3
Me tāpiri te 3 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
