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 $x$

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

Step2: Solve for $x$

Divide by 2 on both sides:
$\frac{2x}{2} = \frac{6}{2}$
$x = 3$

(Graph note: To solve via graph, plot $y=2x-1$ and $y=5$. The $x$-coordinate of their intersection is the solution, which is 3.)

Answer:

$x=3$
