which of the following shows the graphical representation of the solution for the one-variable linear equation 2x-1=3

Andrej [43]

For this case we have the following equation:

$2x-1 = 3$

If we add 1 to both sides of the equation we have:

$2x = 3 + 1\\2x = 4$

Dividing between 2 on both sides of the equation we have:

$x = \frac {4} {2}\\x = 2$

The graph of the solution is shown in the attached figure.

Answer:
