-14=-2\left(2x+1\right)
Variable x cannot be equal to -\frac{1}{2} since division by zero is not defined. Multiply both sides of the equation by 2x+1.
-14=-4x-2
Use the distributive property to multiply -2 by 2x+1.
-4x-2=-14
Swap sides so that all variable terms are on the left hand side.
-4x=-14+2
Add 2 to both sides.
-4x=-12
Add -14 and 2 to get -12.
x=\frac{-12}{-4}
Divide both sides by -4.
x=3
Divide -12 by -4 to get 3.
