3x-18=2\left(x+4\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-6.
3x-18=2x+8
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+4.
3x-18-2x=8
Tangohia te 2x mai i ngā taha e rua.
x-18=8
Pahekotia te 3x me -2x, ka x.
x=8+18
Me tāpiri te 18 ki ngā taha e rua.
x=26
Tāpirihia te 8 ki te 18, ka 26.
