-7

Explanation:

Write an equation.

  • Since it says "12 more" then you can assume that it means 12 +
  • "a number" can be represented as #n#
  • The total is 5

So we can write it out as:
12 + n = 5

Solve for #n# by isolating it. Which means to subtract 12 from both sides.
#12 - 12 + n = 5 - 12#
# n = -7#

The number is equal to -7.

Check
#12 + (-7) = 5#
