Answer:

-4x - 6

Step-by-step explanation:

2(x + 2) = 2x + 4

3(-x - 2) = - 3x- 6

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

Add these binomials together

2x - 3x - 2x = -3x

4 - 6 - 4 = - 6

Result

-3x - 6

Now to this result we must subtract an x

-3x - x - 6 = - 4x - 6

Answer:

[tex]\boxed{\tt -4x-6}[/tex]

Step-by-step explanation:

[tex]\tt 2(x +2) - x +3 (-x -2) -(2x +4)[/tex]

First, apply the (Distributive property):-

[tex]\boxed{\tt -\left(a+b\right)=-a-b}[/tex]

[tex]\tt 2\left(x+2\right)-x+3\left(-x-2\right)-2x-4[/tex]

Expand, (Apply Distributive property):-

[tex]\tt 2\left(x+2\right)= \underline{\tt 2x+4}[/tex]

[tex]\tt 3\left(-x-2\right)=\underline{\tt -3x-6}[/tex]

[tex]\tt 2x+4-3x-6-3x-4[/tex]

Combine like terms:-

[tex]\tt (2x-3x-3x)+(4-6-4)[/tex]

[tex]\tt (2x-3x-3x)=\underline{\bold{ -4x}}[/tex]

[tex]\tt (4-6-4)=\underline{\bold{ -6}}[/tex]

[tex]\tt -4x-6[/tex]
