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
