Kua tāruatia ki te papatopenga
2\left(2x-4\right)+2=-x
Me whakarea ngā taha e rua o te whārite ki te 14, arā, te tauraro pātahi he tino iti rawa te kitea o 7,14.
4x-8+2=-x
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 2x-4.
4x-6=-x
Tāpirihia te -8 ki te 2, ka -6.
4x-6+x=0
Me tāpiri te x ki ngā taha e rua.
5x-6=0
Pahekotia te 4x me x, ka 5x.
5x=6
Me tāpiri te 6 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{6}{5}
Whakawehea ngā taha e rua ki te 5.
