Kua tāruatia ki te papatopenga
2x-2=-x+5
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-1.
2x-2+x=5
Me tāpiri te x ki ngā taha e rua.
3x-2=5
Pahekotia te 2x me x, ka 3x.
3x=5+2
Me tāpiri te 2 ki ngā taha e rua.
3x=7
Tāpirihia te 5 ki te 2, ka 7.
x=\frac{7}{3}
Whakawehea ngā taha e rua ki te 3.
