"If you subtract 17 from my number and multiply the difference by negative 4, the result is negative 92.
n= number
(n-17)*(-4) = -92
distribute
-4 *n - 17*(-4) = -92
-4n +68 = -92
subtract 68 from each side
-4n +68-68 = -92 -68
-4n = -160
divide each side by -4
-4n/-4 = -160/-4
n = 40
Julio's number is 40
