Use the terms 4,12a,6,2a, and 24 to make equivalent expressions. use each term only once. use substitution to prove that the expressions are equivalent

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!
