2x-6=12-x
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-3.
2x-6+x=12
Me tāpiri te x ki ngā taha e rua.
3x-6=12
Pahekotia te 2x me x, ka 3x.
3x=12+6
Me tāpiri te 6 ki ngā taha e rua.
3x=18
Tāpirihia te 12 ki te 6, ka 18.
x=\frac{18}{3}
Whakawehea ngā taha e rua ki te 3.
x=6
Whakawehea te 18 ki te 3, kia riro ko 6.
