Final answer:
The equation representing the given description is 8x - 5 = 11. To solve the equation, add 5 to both sides, then divide both sides by 8 to find x = 2.
Step-by-step explanation:
The equation that represents the description 'five less than eight times a number x equals eleven' is 8x - 5 = 11.
To solve this equation, you can add 5 to both sides to isolate the term with x: 8x = 16. Then, divide both sides by 8 to solve for x: x = 2.
So the solution to the equation is x = 2.
