For this case we have the following equation:
[tex]2x-1 = 3[/tex]
If we add 1 to both sides of the equation we have:
[tex]2x = 3 + 1\\2x = 4[/tex]
Dividing between 2 on both sides of the equation we have:
[tex]x = \frac {4} {2}\\x = 2[/tex]
The graph of the solution is shown in the attached figure.
