We are asked to evaluate Marlena's solution in solving the expression below: 2x+5 = - 10 - x

The first step is to re-write the expression and transpose same terms in the left side while all numbers are transferred to the right side such as shown below:

Step 0: 2x+5 = - 10 - x

Step 1: 2x + x = - 10 - 5

Step 2: 3x = - 15

Step 3: x = - 15/3

The answer is x=-5.
