In this problem, our best option is to just guess-and-check.

6 (2a + 4) = 12a + 24

Now let's check this!

Distribute the 6:: 12a + 24 = 12a + 24

Both sides look the same so that's our answer.

And there you have it! 6 (2a + 4) = 12a + 24 is your final equation. You can split up both sides into individual expressions (writing them separately without = ).

For using substitution, choose a random number for a and put it into both separate expressions, and they should result in the same number.

Ex. a = 1

6 (2+4) = 6 (6) = 36. 12+24=36

And that should be it for this question!
