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.

Given :
[tex]2x+5=-10-x[/tex]
Solution :
Step 1 : Collect the like terms,
[tex]2x+x+5=-10[/tex]
[tex]3x+5=-10[/tex]
Step 2 : Subtract 5 from both sides of the equation (Subtraction property of equality)
[tex]3x+5-5=-10-5[/tex]
[tex]3x=-15[/tex]
Step 3 : Divide both sides by 3 (Division property of equality)
[tex]\dfrac{3x}{3}=-\dfrac{15}{3}[/tex]
[tex]x=-5[/tex]
The value of x is -5 and the steps taken are: Collect the like terms, Subtraction property of equality and Division property of equality.
