Hi!

Let's start with the facts:

  1. She had m messages
  2. They divided m messages into 4 equal groups
  3. Each of those groups had 43 messages
  4. We must solve using a division equation

Therefore:

[tex]\frac{m}{4}=43[/tex]

Now, we have an algebraic equation. In order to solve, we must multiply both sides by 4 so that way m is by itself.

[tex]\frac{m}{4}*4=43*4[/tex]

[tex]m=172[/tex]

Therefore, Mandy received 172 messages. (that's a lot of messages!)
