Answer: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.
