4x-4-2-x=6-3\left(x-12\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x-1.
4x-6-x=6-3\left(x-12\right)
Tangohia te 2 i te -4, ka -6.
3x-6=6-3\left(x-12\right)
Pahekotia te 4x me -x, ka 3x.
3x-6=6-3x+36
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te x-12.
3x-6=42-3x
Tāpirihia te 6 ki te 36, ka 42.
3x-6+3x=42
Me tāpiri te 3x ki ngā taha e rua.
6x-6=42
Pahekotia te 3x me 3x, ka 6x.
6x=42+6
Me tāpiri te 6 ki ngā taha e rua.
6x=48
Tāpirihia te 42 ki te 6, ka 48.
x=\frac{48}{6}
Whakawehea ngā taha e rua ki te 6.
x=8
Whakawehea te 48 ki te 6, kia riro ko 8.
