The table shows the solution to the equation |2x − 5| − 2 = 3:




Step 1
|2x − 5| = 3 + 2


Step 2
|2x − 5| = 5

Step 3
2x − 5 = 5 or 2x − 5 = −5

Step 4
2x = 10 or 2x = 0

Step 5
x = 5 or x = 0


Which is the first incorrect step?
A. Step 3 B.Step 4 C.Step 5 D.Solution is correct

Respuesta :

First add 2 to both sides, next add 2 + 3 to get 5, next break down the equation into two problems which would be 2x - 5 = 5 and -(2x - 5) = 5, NOT 2x - 5 = -5, so this is the FIRST incorrect step, while step 4 is incorrect because its suppose to be 2x = 5 not 10, that's the second step, not first so answer is:

Answer: A) Step 3.
