3x+6+5=2\left(x+15\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+2.
3x+11=2\left(x+15\right)
Tāpirihia te 6 ki te 5, ka 11.
3x+11=2x+30
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+15.
3x+11-2x=30
Tangohia te 2x mai i ngā taha e rua.
x+11=30
Pahekotia te 3x me -2x, ka x.
x=30-11
Tangohia te 11 mai i ngā taha e rua.
x=19
Tangohia te 11 i te 30, ka 19.
