2x-6=3\left(x+2\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-3.
2x-6=3x+6
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+2.
2x-6-3x=6
Tangohia te 3x mai i ngā taha e rua.
-x-6=6
Pahekotia te 2x me -3x, ka -x.
-x=6+6
Me tāpiri te 6 ki ngā taha e rua.
-x=12
Tāpirihia te 6 ki te 6, ka 12.
x=-12
Me whakarea ngā taha e rua ki te -1.
