$x = -1$

Step 1) Subtract $1$ from each side of the equation to isolate the $x$ variable and keep the equation balanced:

$2x + 1 - 1 = -1 - 1$

$2x + 0 = -2$

$2x = -2$

Step 2) Divide each side of the equation by $2$ to solve for $x$ and keep the equation balanced:

$(2x)/2 = -2/2$

$(cancel(2)x)/cancel(2) = -1$

$x = -1$
