Answer:
[tex]12x-6[/tex]
Step-by-step explanation:
For our first step, let's rearrange our equation to get our variable terms (8x and 4x) and our constants (the two 3's) together:
[tex]8x+4x-3-3[/tex]
Taking away 3 twice is the same as taking away 6, and if we have 8 x's and add another 4 x's, that's the same as 8 + 4 = 12 x's, which we can write as 12x. So our simplified expression becomes
[tex]12x-6[/tex]
