x+(x+1)=2x+1
1. 2x+1=61
\(\displaystyle{x}=\frac{{60}}{{2}}\)
x=30
2. 2x+1=35
\(\displaystyle{x}=\frac{{34}}{{2}}\)
x=17
3. 2x+1=91
\(\displaystyle{x}=\frac{{90}}{{2}}\)
x=45
4. 2x+1=125
\(\displaystyle{x}=\frac{{124}}{{2}}\)
x=62
5. 2x+1=-17
\(\displaystyle{x}=-\frac{{18}}{{2}}\)
x=-9
6. 2x+1=-81
\(\displaystyle{x}=-\frac{{82}}{{2}}\)
x=-41
