4x-6=-2x+6
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 2x-3.
4x-6+2x=6
Me tāpiri te 2x ki ngā taha e rua.
6x-6=6
Pahekotia te 4x me 2x, ka 6x.
6x=6+6
Me tāpiri te 6 ki ngā taha e rua.
6x=12
Tāpirihia te 6 ki te 6, ka 12.
x=\frac{12}{6}
Whakawehea ngā taha e rua ki te 6.
x=2
Whakawehea te 12 ki te 6, kia riro ko 2.
