7+2x-6-\left(x-1\right)=x+5-\left(x-1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-3.
1+2x-\left(x-1\right)=x+5-\left(x-1\right)
Tangohia te 6 i te 7, ka 1.
1+2x-x-\left(-1\right)=x+5-\left(x-1\right)
Hei kimi i te tauaro o x-1, kimihia te tauaro o ia taurangi.
1+2x-x+1=x+5-\left(x-1\right)
Ko te tauaro o -1 ko 1.
1+x+1=x+5-\left(x-1\right)
Pahekotia te 2x me -x, ka x.
2+x=x+5-\left(x-1\right)
Tāpirihia te 1 ki te 1, ka 2.
2+x=x+5-x-\left(-1\right)
Hei kimi i te tauaro o x-1, kimihia te tauaro o ia taurangi.
2+x=x+5-x+1
