3+3x=-\left(1-x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 1+x.
3+3x=-1-\left(-x\right)
Hei kimi i te tauaro o 1-x, kimihia te tauaro o ia taurangi.
3+3x=-1+x
Ko te tauaro o -x ko x.
3+3x-x=-1
Tangohia te x mai i ngā taha e rua.
3+2x=-1
Pahekotia te 3x me -x, ka 2x.
2x=-1-3
Tangohia te 3 mai i ngā taha e rua.
2x=-4
Tangohia te 3 i te -1, ka -4.
x=\frac{-4}{2}
Whakawehea ngā taha e rua ki te 2.
x=-2
Whakawehea te -4 ki te 2, kia riro ko -2.
