Julio says if you subtract 17 from my number and multiply the difference by - 2 the result is gonna be negative 12 what was Julio Number

23

Step-by-step explanation:

Taking an algebraic approach

let the number be n, then (n - 17) is 17 subtracted from number and

- 2 (n - 17) = - 12 (divide both sides by - 2)

n - 17 = 6 (add 17 to both sides)

n = 23

Thus Julio's number was 23
