Answer 2

Answer:

x=-1

Step-by-step explanation:

Step 1 :Pulling out like terms

1.1     Pull out like factors :

  -2x - 2  =   -2 • (x + 1)

Equation at the end of step 1 :

Step 2 :

Equations which are never true:

2.1      Solve :    -2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

2.2      Solve  :    x+1 = 0

Subtract  1  from both sides of the equation :

                     x = -1

One solution was found :

x = -1
