6x+6=3x+3
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te x+1.
6x+6-3x=3
Tangohia te 3x mai i ngā taha e rua.
3x+6=3
Pahekotia te 6x me -3x, ka 3x.
3x=3-6
Tangohia te 6 mai i ngā taha e rua.
3x=-3
Tangohia te 6 i te 3, ka -3.
x=\frac{-3}{3}
Whakawehea ngā taha e rua ki te 3.
x=-1
Whakawehea te -3 ki te 3, kia riro ko -1.
