Test 3 Section 5 - #14 (page 529)

When the SAT spells out an equation in words instead of just giving it to you, it's usually going to be a very simple equation once you translate it.  Most of the translating is pretty easy:

  • "Five times a number" can be translated to "5n"
  • "the number added to 5" can be translated to "n + 5"
  • "is the same as" has to mean just "="
So we rewrite what they spelled out, and solve it:
5n = n + 5
4n = 5
n = 5/4 or 1.25
