Final answer:
To solve the given expression, simplify both sides of the equation and then multiply them together. None of the given expressions are equivalent to the original expression.
Step-by-step explanation:
To solve the given expression, we need to simplify both sides of the equation and then multiply them together:
(1/3x - 5/3x) - (-4/3x * 2)
To simplify the left side of the equation, we need to find a common denominator for the fractions:
(1 - 5)/3x = -4/3x
Now, we can combine like terms:
-4/3x - (-8/3x) = -4/3x + 8/3x = 4/3x
Therefore, the expression is equivalent to 4/3x, which is not one of the given options. None of the given expressions are equivalent to the original expression.
