Kua tāruatia ki te papatopenga
2-\left(3-2x-2\right)=3x+2\left(x-\left(3+2x\right)\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x+1.
2-\left(1-2x\right)=3x+2\left(x-\left(3+2x\right)\right)
Tangohia te 2 i te 3, ka 1.
2-1-\left(-2x\right)=3x+2\left(x-\left(3+2x\right)\right)
Hei kimi i te tauaro o 1-2x, kimihia te tauaro o ia taurangi.
2-1+2x=3x+2\left(x-\left(3+2x\right)\right)
Ko te tauaro o -2x ko 2x.
1+2x=3x+2\left(x-\left(3+2x\right)\right)
Tangohia te 1 i te 2, ka 1.
1+2x=3x+2\left(x-3-2x\right)
Hei kimi i te tauaro o 3+2x, kimihia te tauaro o ia taurangi.
1+2x=3x+2\left(-x-3\right)
Pahekotia te x me -2x, ka -x.
1+2x=3x-2x-6
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te -x-3.
1+2x=x-6
Pahekotia te 3x me -2x, ka x.
1+2x-x=-6
Tangohia te x mai i ngā taha e rua.
1+x=-6
Pahekotia te 2x me -x, ka x.
x=-6-1
Tangohia te 1 mai i ngā taha e rua.
x=-7
Tangohia te 1 i te -6, ka -7.
