Question

here is an equation.
2x - 1 = 5
draw a graph to help solve the equation. then find the solution to the equation.
solution: x = \square

Explanation:

Step1: Rearrange to isolate $2x$

Add 1 to both sides.
$2x - 1 + 1 = 5 + 1$
$2x = 6$

Step2: Solve for $x$

Divide both sides by 2.
$x = \frac{6}{2}$

Answer:

$x = 3$

To solve via graphing:

1. Graph $y=2x-1$ (a line with slope 2, y-intercept -1)
2. Graph $y=5$ (a horizontal line at $y=5$)
3. The x-coordinate of their intersection point is 3, which is the solution.
