Answer:
Option B) The simplification performed in step 2 is invalid or incorrect
The value of w in the given expression is -54
Step-by-step explanation:
Option B) The simplification performed in step 2 is invalid or incorrect
The corrected steps are given below :
GIven expression is 
and x=2y
To find w when y=-2 :
Step 1: I first substitute y=-2 into x=2y yielding x=2(-2)
Step2: I simplify the expression resulting in x=-4
Step3: I substitute x=-4 and y=-2 into the given expression we get
Step 4: I use order of operations to simplify and get
Therefore w=-54
The value of w in the given expression is -54

answer:
Hello there!
First of all, I like your profile picture!
1) There's a lot of different methods for solving a system of equation. But here are my three favorite.
- Graphing
- Substitution (Which I preferred to use and I think it is easier).
- Elimination
2) When solving a system of equations, you can get;
- One solution
- No solution
- Infinite number of solution
3) The graphing method help solving a system of equation by knowing that the solution to a system of equations is the point of intersection of the two lines.
