The correct answer is D.
The process has an error from step 3 to step 4.
The correct step 4 should be: x=(c-b-2)/2.
Solve the equation for x: 2x+b=c
check this process:
Step 1: 2x+b-b=c-b
Step 2: 2x=c-b
step 3: 2x-2=c-b-2
Step 4: x=c/2-B-2
Check all of the choices that are true statements
A. There is no error in the process
B. The process has an error from step 1 to step 2
C.the process has an error from step 2 to step 3
D. The process has an error from step 3 to step 4
