Final answer:
To find Julio's number, we can set up an equation based on the information given and solve for x. The value of x represents Julio's number.
Step-by-step explanation:
To find Julio's number, let's call it x, we can set up an equation based on the information given. According to Julio, if we subtract 17 from his number and multiply the difference by -3, the result is -45. This can be written as: (-3)(x - 17) = -45. To solve for x, we will divide both sides of the equation by -3 to isolate x. (-3)(x - 17) / -3 = -45 / -3. Simplifying this gives us x - 17 = 15. Finally, we can add 17 to both sides of the equation to find the value of x. x = 15 + 17. Therefore, Julio's number is 32.
