The answer is A and C, because 4(7x + 2 + x) simplifies to 32x + 8, and expressions A and C also simplify to 32x + 8. I hope this helps!
Keep doing each step manually, and see where it slips up:
−7.9+8.2−3.4+2.1=−1
−7.9+8.2+(−3.4)+2.1=−1
−7.9+(−3.4)+8.2+2.1=−1
(−7.9+(−3.4))+(8.2+2.1)=−1
−11.3+10.3=−1
