Kua tāruatia ki te papatopenga
2x-2=3x+4
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-1.
2x-2-3x=4
Tangohia te 3x mai i ngā taha e rua.
-x-2=4
Pahekotia te 2x me -3x, ka -x.
-x=4+2
Me tāpiri te 2 ki ngā taha e rua.
-x=6
Tāpirihia te 4 ki te 2, ka 6.
x=-6
Me whakarea ngā taha e rua ki te -1.
