Final answer:
To solve the equation 3x - 7 = 0, you add 7 to both sides, then divide by 3, resulting in x = 2.33 when rounded to two decimal places.
Step-by-step explanation:
To solve the equation 3x − 7 = 0 using the single-graph method, first add 7 to both sides to isolate the x-term:
3x = 7
Next, divide each side by 3 to solve for x:
x = ÷ 3
x = 2.33 (rounded to two decimal places)
This solution indicates the value of x when the line y = 3x − 7 crosses the x-axis on a graph, which can be verified using graphical methods by plotting the linear equation and finding the zero.
