first distribute your parenthesis -4x - 5 + 3x = -11
combine like terms: -x - 5 = - 11
add 5 to both sides: -x = -11 + 5 = -6
multiply by -1: x = 6

First: eliminate the parenthesis > use distribution - combine the outer negative sign with the terms in the parenthesis...

- 4x - (5) - (-3x) = -11
- 4x - 5 + 3x = - 11

Sec: combine "like" terms...

- 4x + 3x - 5 = - 11
- x - 5 = - 11

Third: solve for "x" by isolating it on one side > add "5" to both sides (when you move a variable to the opposite side, use the opposite sign)...

- x - 5 + 5 = - 11+5
- x = - 6

*The "x" variable can't be negative which means, change the signs in the equation...

x = 6

You first get rid of the brackets:
secondly group like terms.x's and the numbers, solve
let x be alone or possitive by dividing each side by
-4x-(5-3x)=-11
-4x-5+3x=-11
-4x+3x=-11+5
-x=-6
x=6

the ultimate goal is to be able to solve for x.

first distribute the negative sign by multiplying it to the numbers in the parenthesis:
-4x -5 +3x = -11

next, put the terms with "x" on one side and the rest on the other side.
-4x +3x = -11 +5

now combine the like terms
-x = -6

we solve for x now by dividing both sides by -1 to get rid of the negative sign on the x
x=6

-4x -5 + 3x = -11.
Add 5 to both sides.
-x = -6.
x = 6.

1. -4x - (5 - 3x) = -11
2. -4x - 5 + 3x = -11
3. -x - 5 = -11
4. -x = -6
5. x = 6

dont forget to distribute your negative...

-4x - 5 + 3x = 11
-x - 5 = 11
-x = 16
x=-16

there you go!
