4x-12+18=3\left(x+4\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x-3.
4x+6=3\left(x+4\right)
Tāpirihia te -12 ki te 18, ka 6.
4x+6=3x+12
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+4.
4x+6-3x=12
Tangohia te 3x mai i ngā taha e rua.
x+6=12
Pahekotia te 4x me -3x, ka x.
x=12-6
Tangohia te 6 mai i ngā taha e rua.
x=6
Tangohia te 6 i te 12, ka 6.
