For this case we have the following equation:

2x + 5 = -x + (- 1)

Below are the correct steps to solve:

We eliminate the parenthesis taking into account that
+ * - = -

2x + 5 = -x-1

We add "x" to both sides of the equation:

$2x + x + 5 = -x + x-1\\3x + 5 = -1$

We subtract 5 from both sides of the equation:

$3x + 5-5 = -1-5\\3x = -6$

We divide by 3 on both sides of the equation:

$x = \frac {-6} {3}\\x = -2$
