4x-11-x-\left(-6\right)=3\left(x-1\right)-2
Hei kimi i te tauaro o x-6, kimihia te tauaro o ia taurangi.
4x-11-x+6=3\left(x-1\right)-2
Ko te tauaro o -6 ko 6.
3x-11+6=3\left(x-1\right)-2
Pahekotia te 4x me -x, ka 3x.
3x-5=3\left(x-1\right)-2
Tāpirihia te -11 ki te 6, ka -5.
3x-5=3x-3-2
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-1.
3x-5=3x-5
Tangohia te 2 i te -3, ka -5.
3x-5-3x=-5
Tangohia te 3x mai i ngā taha e rua.
-5=-5
Pahekotia te 3x me -3x, ka 0.
\text{true}
Whakatauritea te -5 me te -5.
x\in \mathrm{C}
He pono tēnei mō tētahi x ahakoa.
