4x-8+16=3\left(x+4\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x-2.
4x+8=3\left(x+4\right)
Tāpirihia te -8 ki te 16, ka 8.
4x+8=3x+12
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+4.
4x+8-3x=12
Tangohia te 3x mai i ngā taha e rua.
x+8=12
Pahekotia te 4x me -3x, ka x.
x=12-8
Tangohia te 8 mai i ngā taha e rua.
x=4
Tangohia te 8 i te 12, ka 4.
