Answer:

x=-3

Step-by-step explanation:

So we have the equation:

-2(-x-4)+3=-7-4x

First, distribute the left side:

-2(-x)-2(-4)+3=-7-4x\\2x+8+3=-7-4x

Add values on the left side:

2x+11=-7-4x

Add 7 to both sides. The right side cancels:

(2x+11)+7=(-7-4x)+7\\2x+18=-4x

Subtract 2x from both sides. The left side cancels:

(2x+18)-2x=(-4x)-2x\\18=-6x

Divide both sides by -6:

(-6x)/-6=18/-6\\x=-3

Therefore, x equals -3.

Answer:

x =  - 3

Step-by-step explanation:

- 2( - x - 4) + 3 =  - 7 - 4x

to \: get \: rid \: of \: the \: parenheses \:  \\ distribute \: two \: through \: the \: parentheses

2x + 8 + 3 =  - 7 - 4x

add \: the \: numbers \\  \\2x + 8 + 3 =  - 7 - 4x \\  \\ 2x + 11 =  - 7 - 4x \\  \\ move \:  - 4x \: to \: the \: left - hand \: side \: and\: change \: its \: sign \\  \\ 2x + 4x + 11 = - 7 \\  \\ move \: constant \: to \: the \: right - hand \: side \: and \: change \: its \: sign \\  \\ 2x + 4x =  - 7 - 11 \\  \\ 6x =  - 18 \\  \\ x =  - 3 \\  \\  \\ hope \: this \: helps \:
