#### Answer

$x=-6$

#### Work Step by Step

Multiply the 2 with each term in the brackets:
$2x+6-1=-7$
Combine like terms on the lest side of the equation:
$2x+5=-7$
Isolate the $x$-term:
$2x=-7-5$
Combine like terms on the right side of the equation:
$2x=-12$
Divide both sides by 2:
$\frac{2x}{2}$ =$\frac{-12}{2}$
Final answer:
$x=-6$
