Suppose you needed to subtract a from b but mistakenly subtract b from a instead. how is the answer you get related to the correct answer. explain.

I would assume you would get a negative number and a positive number either way, but they would be the same number just one is negative and one is positive

The answer to your question is d 68%

1. use commutative property to reorder the terms.2x+81=0.2. move the constant to right side by adding its opposite on both sides. 2x+81-81=0-81.2x=(-81).3. divide the equation on both sides.2x ÷ 2 = 81 ÷ 2.x = -81/2. your answer is -81/2. if you need to simplify it into a decimal, it’s -40.5.
