Question

On Thursday, Mandy receives m messages. she doesn’t have time to read them,

Answer 1

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:

$\frac{m}{4}=43$

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

$\frac{m}{4}*4=43*4$

$m=172$

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

For another example of solving an equation algebraically, see:

Answer 2

Let the number of messages be m

Since every friend has read 43 messages, The equation formed will be

$m \div 4 = 43$

Move the constant to the right hand side and change its sign to multiplication

$m = 43 \times 4$

Multiply the numbers

$m = 172$

Thus, Mandy had 172 messages!!~
