The table shows the solution to the equation |2x − 4| − 3 = 3:

step 1: |2x − 4| = −3 + 3
step 2: |2x − 4| = 0
step 3: 2x − 4 = 0
step 4: 2x = 4
step 5: x = 2

which is the first incorrect step?

a.step 1
b.step 2
c.step 3
d.solution is correct

The correct answer is:

A.Step 1

Explanation:

The first step to solving this equation would be to cancel the 3, since it is outside the absolute value bars.  To cancel subtraction, we would add; this would give us

|2x-4| = 3+3

Instead, we had |2x-4| = -3+3

Thus the first step is incorrect.
