Which expression is equivalent to −4.7+(−0.3)+(−1.4)−4.7+(−0.3)+(−1.4) ?

−4.7−(0.3−1.4)−4.7−(0.3−1.4)

−(4.7+0.3+1.4)−(4.7+0.3+1.4)

(4.7+0.3)+(−1.4)(4.7+0.3)+(−1.4)

−4.7+(0.3+1.4)

I need this answered within 10 minutes, and please explain how your answer may be correct so I have proof. If I get this correct I'll mark your comment the brainliest. :) good luck

The answer is B. 

WORK: −(4.7+0.3+1.4)−(4.7+0.3+1.4)=−(5+1.4)−(4.7+0.3+1.4)=−6.4−(4.7+0.3+1.4)=−6.4−(5+1.4)=−6.4−6.4=−12.8   
 
And that answer is equivalent to the original equation.

Work: −4.7−0.3−1.4−4.7−0.3−1.4=−5−1.4−4.7−0.3−1.4=−6.4−4.7−0.3−1.4=−11.1−0.3−1.4=−11.4−1.4=−12.8

ok so first I solved the original problem and got -12.8, then i solved all the other ones to see which one gets the same answer. The following answers are in order according to the problem

-7.2
-12.8
-3.4
-3

So the answer would be the second one because it has the same answer as the original problem
