Which of the following is a simplified form of4x-4y+ 3x?
Correct answer: D. 7x-4y
- A. x(7-4y)
- B. x - y + 3x
- C. -8xy + 3x
- D. 7x-4y
- E. -4y-x
Explanation
To simplify the expression 4x - 4y + 3x, first combine the like terms, which are the terms involving 'x'. Add 4x and 3x to get 7x. Thus, the simplified expression becomes 7x - 4y, which is Option D. The other options do not correctly simplify the expression:Option A incorrectly factors the expression.Option B does not combine the like terms correctly.Option C introduces incorrect terms.Option E rearranges terms without proper combination.
