What is the answer i'll give brainly

egoroff_w [7]

Answer:

c = -3

Step-by-step explanation:

Multiply all terms by the same value to eliminate fraction denominators

$4(-2)=4*\frac{-c-11}{4}$

Cancel multiplied terms that are in the denominator

$4(-2)=-c-11$

Multiply the numbers

$-8=-c-11$

Add 11 to both sides of the equation

$-8+11=-c-11+11$

Simplify

$3=-c$

Divide both sides of the equation by the same term

$\frac{3}{-1}=\frac{-c}{-1}$

Simplify

$c=-3$
