What is the​ error?
A. The right side of the equation should be 6 after dividing each side by -4.
B. The right side of the equation should be 8 after subtracting -8 from each side.
C. The left side of the equation should be - r after dividing each side by -4.
D. The left side of the equation should be - 8+4r after distributing.

Answer 1

D

Explanation:

Honestly I can't giv a detailed explanation, apologies. Negatives multiplied result in positives. Since -4 is negative and -r is also negative, expanded form should be +4r. Also the answer is r=6 in case you need it.

Answer 2

The answer is D

Explanation:

- x - equals positive so it would be -8+4r
