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!
