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 [tex]w+xy+3x^2=2[/tex] 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 [tex]w+xy+3x^2=2[/tex] we get

[tex]w+(-4)(-2)+3(-4)^2=2[/tex]

Step 4: I use order of operations to simplify and get

[tex]w+8+3(16)=2[/tex]

[tex]w=2-56[/tex]

Therefore w=-54

The value of w in the given expression is -54
