1. The solution of the word problem is -2. Julio’s number is -2

   How to find Julio’s number?

   A word problem is a mathematical exercise where significant background information on the problem is presented in ordinary language rather than in mathematical notation

   Let Julio’s number be x

   If you subtract 12 from Julio’s number, you will have:

   x-12

   When you multiply the difference by -7, you will have:

   -7(x-12)

   Given that the result is -98. That means:

   -7(x-12) = -98

   Solve for x:

   -7(x-12) = -98   (Expand the parenthesis)

   -7x + 84 = 98

   -7x = 98-84

   -7x = 14

   x = 14/(-7)

   x = -2

   Thus, Julio’s number is -2
