It wouldn’t let me cancel to answer this but i do not know the answer and i had to type something to exit it. i’m sorry
Get rid of brackets:
21x +6 +8x
Put 6 to the other side:
21x +8x = -6
27x = -6
Divide both sides by 27
X= -0.22
That’s hard umm idk look it up and it will tell you
The answer is
X=10 or X= -4
