10-2x+2\left(2x-1\right)=3x-2
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 5-x.
10-2x+4x-2=3x-2
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 2x-1.
10+2x-2=3x-2
Pahekotia te -2x me 4x, ka 2x.
8+2x=3x-2
Tangohia te 2 i te 10, ka 8.
8+2x-3x=-2
Tangohia te 3x mai i ngā taha e rua.
8-x=-2
Pahekotia te 2x me -3x, ka -x.
-x=-2-8
Tangohia te 8 mai i ngā taha e rua.
-x=-10
Tangohia te 8 i te -2, ka -10.
x=10
Me whakarea ngā taha e rua ki te -1.
