5x-10=3\left(2x+2\right)+2
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x-2.
5x-10=6x+6+2
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2x+2.
5x-10=6x+8
Tāpirihia te 6 ki te 2, ka 8.
5x-10-6x=8
Tangohia te 6x mai i ngā taha e rua.
-x-10=8
Pahekotia te 5x me -6x, ka -x.
-x=8+10
Me tāpiri te 10 ki ngā taha e rua.
-x=18
Tāpirihia te 8 ki te 10, ka 18.
x=-18
Me whakarea ngā taha e rua ki te -1.
