Question

Which expression is equivalent to (4x – 5) – (-3x + 4)?

Answer 1

(4x -5) - (-3x +4) equals to 7x - 9

Answer 2

(4x – 5) – (-3x + 4) can be simplified by distributing the negative sign to the terms inside the parentheses:

(4x - 5) + (3x - 4)

We can then combine like terms by adding the coefficients of x and the constants:

7x - 9

Therefore, the expression that is equivalent to (4x – 5) – (-3x + 4) is 7x - 9.
