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

ANswer:


x = -2
