x+4+2\left(x-2\right)=6
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 6,3.
x+4+2x-4=6
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-2.
3x+4-4=6
Pahekotia te x me 2x, ka 3x.
3x=6
Tangohia te 4 i te 4, ka 0.
x=\frac{6}{3}
Whakawehea ngā taha e rua ki te 3.
x=2
Whakawehea te 6 ki te 3, kia riro ko 2.
