4x - (2 - x) can be simplified by opening the brackets and applying the signs correctly.
4x - 2 - ( -x) = 4x - 2 + x ( - of - is plus)
5x - 2 is the result.

This requires distributing the negative sign (really multiplying by -1):
4x - 2 -(-x) = 4x - 2 + x = 5x - 2

a million) 4x - 2y + 3x + y = 4x + 3x - 2y + y = 7x - y 2) 2x^2 - 2x + 6x - 5 - x^3 + 4x^2 = -x^3 + 2x^2 + 4x^2 + 4x - 5 = -x^3 + 6x^2 + 4x - 5 3) 2ab - a + b + 2a - 6ab + 2b + b^2 = -a + 2a + 2ab - 6ab + b^2 + b + 2b = a - 4ab + b^2 + 3b

This simplifies to 4x minus minus x = 5x. So we have 5x - 2

4x-(2-x)
4x -2 +x <-- Remove parentheses, paying attention to signs
5x -2 <-- Collect like terms. That's it!

4x-(2-x)
4x-2+x --distribute the negative
5x-2 --combine like terms.

4x - (2-x) = 4x - (+2) - (-x) = 4x - 2 + x = 4x + x - 2 = 5x - 2
